Question

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?

Answer 1

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:

`m\angle SRP=90º.`

Answer:

`m\angle SRP=90º.`
