In circle s, what is the value of x?

enter your answer in the box. x = °

We are asked to solve for the value of "x" in the problem. In the circle property, assuming that S is the diameter of the circle, we can say that the angle facing the diameter is 90°.

We have the summation of all angles in a triangle equal to 180°. Solving for x, we have:
180 ° = x + 90° + 39°
x = 180° - 90° -39°
x = 51°

The answer for "x" value is 51°. 

This is too long-standing now get out
