Any circle that can given by

have a center of

You can choose
any positive value for the radius

Hence, there are infinity circles.
X+7x=180
8x=180
x= 22.5
the larger angle is 157.5 degrees.
Answer:
x = 3/2 v - 3 (or x = 3v/2 - 3)
Step-by-step explanation:
v = 2/3 x + 2
v - 2 = 2/3 x
3/2 v - 3 = x
