Question

In the diagram below, if the line AC is tangent to the circle with the center P, then the measure of the angle formed by < PBA I

Answer 1

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Define the tangent to a circle

A tangent is a straight line that touches the circumference of a circle at only one place.

The tangent line AC touches the circle at P.

The radius of the circle PB is perpendicular to the tangent AC at the point of contact P.

`\begin{gathered} PB\text{ IS PERPENDICULAR TO AB} \\ \text{AND } \\ \angle PBA=90\degree \end{gathered}`

Hence, the angle formed by
