Question

I need help with this stuff I don’t understand

Answer 1

I don’t know either

Answer 2

x = 10°

Explanation:

By the inscribed angle theorem, the measure of an inscribed angle is half the measure of the intercepted arc.

So

x =( x + 10 )/2

2x = x + 10

2x - x = 10

x = 10°

Hope it will help :)
