Answer 1

9514 1404 393

Answer:

  30

Step-by-step explanation:

The triangle inside the circle is an equilateral triangle, so the central angle is 60°. That angle is one of the acute angles in the right triangle formed by the tangent line. The other acute angle (x°) in that right triangle is the complement of 60°.

  x° = 90° -60° = 30°

  x = 30
