Find the missing angle measurements.
(not all will be used)
Answers
B.) 64°
C.) 45°
Angle B is 64° because the angle in front of it is also 64°. They carry the same measurement because they are alternate interior angles.
You can find C by computing the measurement of the rest of the triangle, 64+71 which is 135. Since a triangle has a complete measure of 180° you subtract 135 from 180, leaving you 45°.
And you can find A in the same manner you found c, by computing the rest of the triangle and subtracting it from 180°, 180- 120 = 60.

Angle 4 = 31 degree
Angle 5 = 59 degree
Step-by-step explanation:
According to the question, angle 3 is 90 degree and the sum of angle 4 and 5 is equal to the angle 3 as they are vertically opposite angles.
Angle 4 + angle 5 = 90 degree
Angle 4 = 2 x - 5
angle 5 = 4 x - 13
So, according to the question,
2 x - 5 + 4 x - 13 = 90
6 x - 18 = 90
6 x = 108
x = 18
So, angle 4 = 2 (18) - 5 = 31 degree
So, angle 5 = 4 (18) - 13 = 59 degree

The volume is42.39
A cone with a base circumference of 6 pi and a height equal to half the radius. The volume of the cone is 42.39.
What is the volume of a cone?The volume of the cone is the product of one-third of the height, pie, and square of the radius.
The volume of the cone = 1/3 [tex]\pi r^{2} h[/tex]
A cone with a base circumference of 6 pi and a height equal to half the radius.
The circumference of the circular base = 2πr
6π = 2πr
r = 3
The radius of the circular base of a cone is 3 unit.
A height equal to half the radius. Thus, the height is 1.5
The volume of the cone = 1/3 [tex]\pi r^{2} h[/tex]

what is the slope that passes through the points : (-2,9) and (4,-7)
Answers
Use the slope formula below:
[tex] \large \boxed{m = \frac{y_2 - y_1}{x_2 - x_1} }[/tex]
The m-term represents the slope.
The formula is the changes of two y-points over the changes of two x-points. We are given two points. Substitute both points in the formula.
[tex] \large{m = \frac{9 - ( - 7)}{ - 2 - 4} } \\ \large{m = \frac{9 + 7}{ - 6} \longrightarrow \frac{16}{ - 6} } \\ \large{m = \frac{8}{ -3 } \longrightarrow - \frac{8}{3} }[/tex]
Therefore the slope is -8/3
Answer
the slope is -8/3Hope this helps! Let me know if you have any doubts.
Answer:
y = -8 / 3x + 11/3
Step-by-step explanation:
Using the slope formula:
[tex]slope = y = \frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}[/tex]
1. Select one point to be [tex](x_{1} ,y_{1} )[/tex] and the other [tex](x_{2} ,y_{2} )[/tex]
I chose (-2, 9) to be [tex](x_{1} ,y_{1} )[/tex] and (4, -7) to be [tex](x_{2} ,y_{2} )[/tex]
2. Plug the values into the formula:
[tex]y = \frac{-7-9}{4-(-2)} \\\\y= \frac{-16}{6} \\\\y = \frac{-8}{3}[/tex]
3. Finding the c-value by plugging in one of the points into the equation
y = mx + c
9 = -8/3 (-2) + c
9 = 16/3 + c
c = 11/3
4. y = -8/3x + 11/3

Step-by-step explanation:
/_ ACB = 180
/_ ACD = 55
/_ ACB is made up of /_ACD and
/_ DCB
Hence, /_ ACB = /_ ACD + /_ DCB
*We then plug in the known values*
180 = 55 + /_ DCB

Subtract 55 from both sides

a) x + 20 = 70 Vertically opposite angles are congruent
b) 2x - 50 = x + 20 Vertically opposite angles are congruent
c) 3x - 10 + 140 = 180 Linear pair
Answer:
(a) 70= x+20 (vertical angles are equal)
70 - 20=x
50=x
(b) x +20 = 2x -50 (vertical angles are equal)
20 + 50 = 2x - x
70 = x
(c) 140 +3x -10=180 (angles on the straight line)
130 +3x = 180
3x = 180 - 130
3x = 50
x= 50/3

Now we know every hour Stella will earn $8. We can now multiply the amount for 1 hour by 23 to get the amount for 23 hours.
8x23=184
1*23=23
Now we can see that Stella would earn $184 for working 23 hours.
