O is the center of the circle. Assume that lines that appear to be tangent are tangent. What is the value of x?

Answers

Given that QO is the radius and PQ is tangent to circle O, then ΔPQO is a right triangle. Hence the value of x will be obtained as follows: Sum of angles in a triangle is equal to 180°. Thus x+17+90=180 x+107=180 thus x=180-107 x=73° Answer: x=73°
