Question

Line I is tangent to circle Q. What is the measure of the angle formed at the point of tangency? 180 degrees 45 degrees 90 degrees 100 degrees

Answer 1

Answer

90 degrees

Explanation:

The tangent line is the line that cuts the circumference of the circle. From the diagram, the line "l" is tangential to the circumference of the circle at point P.

Also, the line PQ is perpendicular to the line l, hence the measure of the angle formed at the point of tangency will be the angle that the line PQ formed with the line "l" which is 90 degrees
