A circle that has a diameter of 10 centimeters. A line is tangent to the circle. What is the angle between the tangent and the diameter at the point of contact?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 90°.
The tangent at the point of contact is perpendicular to the radius (which is half the diameter).
So the angle between the tangent and the diameter is 90°.
