In the adjoining figure , ABC is an isosceles triangle. BO and CO are the bisectors of [tex] \angle[/tex] ABC and [tex] \angle[/tex] ACB respectively. Prove that BOC is an isosceles triangle.
~Thanks in advance !
Here it's given that ∆ABC is a isosceles triangle. We know that in a isosceles triangle opposite angles are equal. And the angles opposite to equal sides are also equal.
Hence here ,
AB = AC ∠ ABC = ∠ACB .Figure :-

If LaTeX doesn't work on app kindly see the attachment .
Here we will use a theorem which is ,
[tex]\large\underline{\underline{\textsf{\textbf{\red{\blue{$\leadsto$} Theorem :- }}}}}[/tex]
Sides opposite to equal angles are equal.Hence here,
[tex]\tt:\implies \angle ABC =\angle ACB \\\\\tt:\implies \dfrac{1}{2}\times \angle ABC = \dfrac{1}{2}\times \angle ACB \\\\\tt:\implies \boxed{\bf \blue{\angle OBC = \angle OCB} }[/tex]
Now in ∆OBC , we can see that ∠OBC = ∠OCB. (just proved ) . Hence we can say that sides OB and OC are equal. Since the sides opposite to equal angles are equal. Therefore in ∆OBC , two sides are equal.
Therefore ∆ OBC is an isosceles triangle.
Hence Proved !Answer:
See Below.
Step-by-step explanation:
We are given the isosceles triangle ΔABC. By the definition of isosceles triangles, this means that ∠ABC = ∠ACB.
Segments BO and CO bisects ∠ABC and ∠ACB.
And we want to prove that ΔBOC is an isosceles triangle.
Since BO and CO are the angle bisectors of ∠ABC and ∠ACB, respectively, it means that ∠ABO = ∠CBO and ∠ACO = ∠BCO.
And since ∠ABC = ∠ACB, this implies that:
∠ABO = ∠CBO =∠ACO = ∠BCO.
This is shown in the figure as each angle having only one tick mark, meaning that they are congruent.
So, we know that:
[tex]\angle ABC=\angle ACB[/tex]
∠ABC is the sum of the angles ∠ABO and ∠CBO. Likewise, ∠ACB is the sum of the angles ∠ACO and ∠BCO. Hence:
[tex]\angle ABO+\angle CBO =\angle ACO+\angle BCO[/tex]
Since ∠ABO =∠ACO, by substitution:
[tex]\angle ABO+\angle CBO =\angle ABO+\angle BCO[/tex]
Subtracting ∠ABO from both sides produces:
[tex]\angle CBO=\angle BCO[/tex]
So, we've proven that the two angles are congruent, thereby proving that ΔBOC is indeed an isosceles triangle.

(8, -56)
(-5,8)
(-9, -23)
(4, 19)
Answer:
(-5,8)
Step-by-step explanation:
The given equation y = -3x - 7 holds true for the ordered pair, so (-5, 8) is a solution. Thus, option third is correct.
To determine whether each ordered pair is a solution to the equation y = -3x - 7, we substitute the x and y values into the equation and check if it holds true.
For the ordered pair (8, -56):
y = -3x - 7
-56 = -3(8) - 7
-56 = -24 - 7
-56 = -31
The equation does not hold true for this ordered pair, so (8, -56) is not a solution.
For the ordered pair (-5, 8):
y = -3x - 7
8 = -3(-5) - 7
8 = 15 - 7
8 = 8
The equation holds true for this ordered pair, so (-5, 8) is a solution.
For the ordered pair (-9, -23):
y = -3x - 7
-23 = -3(-9) - 7
-23 = 27 - 7
-23 = 20
The equation does not hold true for this ordered pair, so (-9, -23) is not a solution.
For the ordered pair (4, 19):
y = -3x - 7
19 = -3(4) - 7
19 = -12 - 7
19 = -19
The equation does not hold true for this ordered pair, so (4, 19) is not a solution.

Step-by-step explanation:

16/4 = 4
2. (8- 4) x 4
8 - 4 = 4
4 x 4 = 16
3. 2^2 + 2^2

2^2 = 4
4 + 4 = 8
Hope I helped!
Answer:
[tex]\frac{4^{2} }{2^{2} } = 4[/tex]
(8 - 4) x 4 = [tex]4^{2}[/tex]
[tex]2^{2} +2^{2}[/tex] = 8
Step-by-step explanation:
[tex]\frac{4^{2} }{2^{2} } = 4[/tex] because [tex]4^{2} = 16[/tex] and [tex]2^{2}[/tex] = 4. 16/4 is the same as 4.
(8 - 4) x 4 = (4) x 4 = 16. This is the same as [tex]4^{2}[/tex].
[tex]2^{2} +2^{2}[/tex] is the same as 4 + 4, which is 8.

how do i solve this? and i have to show my work so help pls
Answer:
1. x-intercept = 3/-5 = -0.60000
y-intercept = 3/1 = 3
2. x-intercept = 3/3 = 1
y-intercept = 3/1 = 3
Step-by-step explanation:
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-5x-3 = 0 and calculate its properties
When y = 0 the value of x is 3/-5 Our line therefore "cuts" the x-axis at x=-0.60000

Carrie is making a temporary ramp from the ground to the top of his patio so that he can roll a cart up to it to move furniture in. The surface of the patio is 3‘9“ above the ground and Gary wants the ramp to have a slope of no more than 0.375. What is the shortest horizontal distance he can have from the base of the patio to the base of the ramp
9514 1404 393
Answer:
10 ft
Step-by-step explanation:
The slope is rise/run. Using Gary's numbers, we have ...
m = rise/run
0.375 ≥ (3.75 ft)/run
run ≥ (3.75 ft)/0.375
run ≥ 10 ft
The shortest horizontal distance to the base of the ramp is 10 feet.

How many expressions can you find using and that have a value of 12 a=6 b=4 c=-2
Answer:
Step-by-step explanation:
Some of the expressions that can be derived that have the values of 12 are:
i. 2a = 2 x 6
= 12
ii. 3b = 3 x 4
= 12
iii. (b + c) x a = (4 - 2) x 6
= 2 x 6
= 12
iv. 2b + [tex]c^{2}[/tex] = (2 x 4) + (-2 x -2)
= 8 + 4
= 12
v. [tex]b^{2}[/tex] - [tex]c^{2}[/tex] = (4 x 4) - (-2 x -2)
= 16 - 4
= 12
vi. [tex]c^{4}[/tex] - b = (-2 x -2 x -2 x -2) + 4
= 16 - 4
= 12

Jorge Claims that the distance between his house and the library is 13 miles. His city is placed on a coordinate plane. Jorge's House is at the coordinates (5, 1), the mall is at coordinates (2, 11) and hte Library is at cordinates (10, 13). What equation verifies his claim?
Answer:
House coordinate = (5, 1)
Library coordinate = (10, 13)
Step-by-step explanation:
Given :
House coordinate = (5, 1)
Library coordinate = (10, 13)
Distance between house snd library :
Distance = sqrt[(x2 - x1)² + (y2 - y1)]
x1 = 5, x2 = 10, y1 = 1, y2 = 13
Distance = sqrt[(10 - 5)² + (13 - 1)²]
Distance = sqrt[(5² + 12²)]
Distance = sqrt(25 +144)
Distance = sqrt(169)
Distance = 13
The sum of two numbers is -6. The difference is 16. Find the two numbers.
Answer:

Step-by-step explanation:
We can write the following system of equations:
[tex]\begin{cases}x+y=6\\x-y=16\\\end{cases}[/tex]
Adding both equations together, we isolate [tex]x[/tex] and get:
[tex]2x=22,\: x=11[/tex]
Plugging [tex]x=11[/tex] in any of the equations, we can solve for [tex]y[/tex]:
[tex]11+y=6,\: y=-5[/tex]
Verify that the solution pair [tex](11, -5)[/tex] works [tex]\checkmark[/tex]

We conclude that:
m∠XWY = 41°Step-by-step explanation:
Given
m∠VWX = 139°
m∠YWZ = 23°
To determine
m∠XWY = ?
We know the measure of the angle of a straight is 180°.
As m∠VWX and m∠XWY lie on a straight line.
Thus, the sum of m∠VWX and m∠XWY must be 180°
so we get the equation
m∠VWX + m∠XWY = 180°
Given that m∠VWX = 139°
so substituting m∠VWX = 139° in the equation m∠VWX + m∠XWY = 180°
139° + m∠XWY = 180°
m∠XWY = 180° - 139°
m∠XWY = 41°
Therefore, we conclude that:
m∠XWY = 41°A right rectangular prism has edge lengths of 1 1/3 inches, 2 inches, and 1 2/3 inches. What is the volume of the prism?
