Answer:
Find the value of x if B is the midpoint of AC, AB = 2x + 9 and BC = 37
Step-by-step explanation:
2[5+2(8-6)]
2[5+2(2)]
2[5+4]
2[9]
18
Answer:

Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form
or 
In this problem we have
y=18 when x=2
Find the value of the constant of proportionality k
----> 
therefore
The equation is equal to

A ) The angle formed by 2 consecutive radii:
Ф= 360° : 8 = 45°
b ) The angle formed by a radius and a side of a polygon:
α = (180° - 45°): 2 = 135° : 2 = 67.5°
Answer:
B ) 45°, 67.5°
Answer: 18 pounds
Step-by-step explanation:
