Answer:
A right angle has a value of 90 degrees (90∘). A right triangle is a triangle in which one angle is a right angle. The relation between the sides and angles of a right triangle is the basis for trigonometry.
The side opposite the right angle is called the hypotenuse (side c in the figure). The sides adjacent to the right angle are called legs (sides a and b). Side a may be identified as the side adjacent to angle B and opposed to (or opposite) angle A. Side b is the side adjacent to angle A and opposed to angle
(A) Two acute angles add to an obtuse angle
(B) Two adjacent angles make a line
(C)Two obtuse angles are supplementary
Decide if each statement is always, sometimes, or never true.
I said never for the first one I’m new to geometry and I’m a freshman I’m taking notes along the way so whatever information you have for me will help!❤️
Answer:
(A) Two acute angles add to an obtuse angle
It's sometimes because for example if you take two acute angles
one is 30 and other is 20
they add to 50 and not greater than 90 so it can be sometimes greater but not always
(B) Two adjacent angles make a line
Its also sometimes because a line means it should be 180 degrees so two adjacent angles can out always be equal to 180 that is a line
(C)Two obtuse angles are supplementary
It's Never true because obtuse angles start from 90 so if you take 91 also and other 91 too so if we add them up that will be 182 not 180
as we know 180 = supplementary angle that's why

Step-by-step explanation:
lilli has $3.65 comprised of quarters and dimes floating on the bottom of her bag she has five more dimes than twice her quarters how many each type of coin does she have? lol pls help
Answer:
7 quaters and 19 dimes
Step-by-step explanation:
Let say x the numbers of quaters,
2*x+5 the numbers of dimes
In cents,: 25*x+10*(2x+5)=365
25x+20x+50=365
45x=365-50
45x=315
x=7
Number of quaters: 7
Number of dimes: 2*7+5=19
Proof:
7*25+10*19=365

by using the formula, we can find :
T7 = [7⁴ - 6(7)³ +23(7)² - 18(7) +24] / 24 =
(2401 - 2058 + 1127 - 126 +24) / 24 =
1368/ 24 = 57
T8 = [8⁴-6(8)³+23(8)²-18(8)+24]/24 =
(4096-3072+1472-144+24)/24 =
2376/ 24 = 99

We know that, Two angles are said to be complementary, if the sum of their measures is 90°.
According to the Question,
⇒ ∠ABD + ∠DBC = 90°
⇒ (2x + 30)° + (3x + 20)° = 90°
⇒ 2x + 30° + 3x + 20° = 90°
⇒ 5x + 50° = 90°
⇒ 5x = 90° - 50°
⇒ 5x = 40°
⇒ x = 40°/5
⇒ x = 8
So, the measure of each angle will be,
⇒ ∠ABD = (2x + 30)°
= 2 × 8 + 30°
= 16 + 30°
= 46°
⇒ ∠DBC = (3x + 20)°
= 3 × 8 + 30°
= 24 + 30°
= 54° ▄▄▄▄▄▄▄▄▄▄▄▄▄▄The ratio of a basketball player's completed free throws to attempted free throws is 4 to 7. If she completed 12 free throws, find how many free throws she attempted.
a. 3 free throws
b. 7 free throws
c. 21 free throws
d. 4 free throws
Answer:
well for Evey 4 completed throws she takes 7 throws
with this ratio we get that;
it's 4:7
there fore
for 12 completed free throws she would take 21 free throws
option c is the answer
hope it's helpful
Answer:
21
Step-by-step explanation:
FreeThrows: FT
Attempted Throws: AT
FT/AT=4/7

Help!! Will give Brainiest
Answer:
add all the rest of the angles, and then subtract the sum from 1080, and that's your ans mate
Answer:
147
Step-by-step explanation:
If you add up all the angles you have, you get 933. Since an octagon has 1080 degree angles the last angle must be added to 933 to make it equal to 1080. If you subtract 933 from 1080, you get the remaining angle 147.

Please help ASAP and explain the answer, thank you
Answer:
Step-by-step explanation:
1) x² - 8x + 5 = 0
2) No subtract 5 from both sides
x² - 8x + 5 - 5 = 0 - 5
x² - 8x = -5
3) Now find (8/2) = 4. Add 4² = 16 to both sides
x² - 8x + 16 = -5 + 16
x² - 8x + 16 = 11
4) (x - 4)² = 11
5) Take square root both sides
x - 4 = ±√11
x = 4 ±√11
Sixteen is equal to 7 increased by the product of 3 and a number.
Answer:
number is 3
Step-by-step explanation:
let the number be n then the product of 3 and the number is 3n , so
16 = 7 + 3n ( subtract 7 from both sides )
9 = 3n ( divide both sides by 3 )
3 = n
That is the number is 3

Profit is always calculated as revenue minus expenses. If a company's expenses were $10 million, write an equation that expresses profit, P, (in millions of dollars) in terms of revenue, R, (in millions of dollars). Then, determine the profit when revenue is $25 million.
a. P= 10-R; $15 million
b. P=R-10; $15 million
c. P=R-10; $35 million
d. P=10-R$35 million
Please select the best answer from the choices provided
Answer: B
Step-by-step explanation:
P=R-$10MM
P = ($25MM)-$10MM
P = $15MM
Emma had 10 Balls in a bag. The balls were numbers 1 through 10. She wanted to test the probability of drawing a ball that is a multiple of 3.
Also, write a prediction about if there is an unlikely, impossible, likely, even, or certain change of drawing a multiple of 3.
Answer:
30%UnlikelyStep-by-step explanation:
The balls - multiples of 3 are:
3, 6 and 9The probability of a multiple of 3 is:
3 out of 10 orP = 3/10 = 30%30% probability is in the range 0%-50% so this event is unlikely
Total multiples=3
[tex]\\ \sf\longmapsto P(3)=\dfrac{Multiples\:of\:3}{Total \:balls}[/tex]
[tex]\\ \sf\longmapsto P(3)=\dfrac{3}{10}[/tex]
[tex]\\ \sf\longmapsto P(3)=30\%[/tex]
It is <50%;So it is unlikely to happen.
pls answer this i need help
Answer:
Step-by-step explanation:
a) Number = x
Multiply it by 3 = 3*x = 3x
Now add 4 to it: 3x + 4
Equation:
3x +4 = 22
b)
3x + 4 = 22
Subtract 4 from both sides
3x + 4 -4 = 22 - 4
3x = 18
Divide both sides by 3
3x/3 = 18/3
x = 6
Answer:
Below in bold.
Step-by-step explanation:
The equation is
3x + 4 = 22
3x = 22 - 4 = 18
x = 18/3
x = 6.

[tex]\text{Suppose the width of the rectangle is }x\text{ cm}[/tex]
[tex]\text{then the perimeter can be expressed as}[/tex]
[tex]2(24+x)=72[/tex]
[tex]24+x=36[/tex]
[tex]x=12[/tex]
[tex]\text{Therefore the area of the rectangle is }24\cdot x=24\cdot 12=288\text{ cm}{}^2[/tex]
Answer: Solution,
length (l) = 24 cm
perimeter (p)= 74 cm
Area (A) = ?
we know,
P = 2(l + b )
74 = 2( 24 + b)
74 = 48 + 2b
2b = 74 - 48
2b = 26
b= [tex]\frac{26}{2}[/tex]
b = 13
now,
A = l*b
= 24 * 13
