Question

Find the value of x. (Note: the line passing through the center of the circle is a diameter)

Answer 1

x = 115

Explanation:

Guys, the answer really is 115. Make sure you double check all the numbers on your problem. Your problem might be the same shape, but different numbers. The verified answer is correct :)

Answer 2

we know that

The measure of the interior angle is the half-summit of the arcs that comprise it and its opposite.

see the attached figure with letters to better understand the problem

measure of the arc ADCB is equal to 180 degrees
arc DC=180-(arc BC+arc AD)----> arc DC=180-(60+70)---> 50°
arc DC=50°
so
∡x=(1/2)*[arc AB+arc DC]---> (1/2)*[180+50]----> ∡ x=115°

the answer is
x=115°
