Answer:
x=45
Step-by-step explanation:
First, this figure takes place half of the circle. So we are dealing with a semi circle.
Angle C is inscribed angle in the semi circle. A semi circle measure 180 degrees. Since Angle C is inscribed, It measures 90 degrees.
This theorem proves this
If an angle is inscribed in a semicircle, it will be half the measure of a semicircle (180 degrees), therefore measuring 90 degrees.
Solve for x
[tex]2x = 90[/tex]
[tex]x = 45[/tex]
