Answer:
mZW=144
Angle x= 72 degrees
Step-by-step explanation:
mZW is equal to 144 because 72 times 2 is equal to 144.
Angle x is equal to 72 degrees because angle y and angle x are equal.

Answer:
y - 6 = -3 ( x - 7)
Step-by-step explanation:
Use one of the points.
m is the slope
The sum of angles of a pentagon is 540°, so x must be chosen to make that so.
85 + 110 + x + 120 + 120 = 540
540 -435 = x = 105
_____
The formula usually used to find the degree measure of the internal angles of an n-sided polygon is (n -2)·180°. For n=5, this is 3·180° = 540°.
