Question

line rt is tangent to circle f at point l, as shown. what is the measure of ∠flr?

Explanation:

Step1: Recall tangent - radius property

A tangent to a circle is perpendicular to the radius at the point of tangency.

Step2: Determine angle measure

Since line $RT$ is tangent to circle $F$ at point $L$ and $FL$ is the radius, $\angle FLR = 90^{\circ}$.

Answer:

$90^{\circ}$
