180
Step-by-step explanation:
We can use the central angle theorem to understand this problem.
The Central Angle Theorem states that the inscribed angle that fall on the opposite side of the circumference is half of the arc subtended by it.
The angle that is on the opposite side of the circumference is a right angle and thus it measures 90°. This is half of the arc labeled x. So x is twice that of 90.
So, x = 180 degrees
