What is the value of X

We know that an inscribed angle is half the degrees of it's intercepted arc.

So,  Angle F = 1/2 Arc GE

8x + 10 = 1/2 (12x + 40)

8x + 10 = 6x + 20

2x = 10

x = 5

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
