PR: 5 in.P70°A circle with center P is shown. RS andST are tangent to circle P.*What is the degree measure of Angle SRP?

Since RS is tangent to circle P, then the tangent and the radius of the circle are perpendiculars.
Now, notice that PR is a radius of circle P, then PR and RS are perpendiculars.
Therefore:
