Answer:

A. 37 degrees

Step-by-step explanation:

Since QR is tangent to the circle, it means that is in a right angle. Meaning that angle Q is equal to 90 degrees.

Since you know what two angles are equal to, you can use the triangle angle sum theorem by setting them all up to 180.

53+90+x=180

Simplify the answer

143+x=180

Subtract 143 from both sides

X=37
