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 line tangent to a circle is perpendicular to the radius at the point of tangency. Here, line $RT$ is tangent to circle $F$ at point $L$, and $FL$ is the radius.

Step2: Determine angle measure

Since $RT\perp FL$, the measure of $\angle FLR = 90^{\circ}$.

Answer:

$90^{\circ}$
