1. Problem Description
We are given a circle with tangent at point . is a straight line. We are given that and . We need to find and .
2. Solution Steps
First, we use the alternate segment theorem, which states that the angle between a tangent and a chord is equal to the angle in the alternate segment. In this case, .
Since , then . Therefore, .
Now, let's find . We know that , and since is a straight line, .
We have .
In triangle , and . We are looking for . Since , we have . Therefore .
The angles in triangle sum up to . Thus, .
We are given .
Since PQ is a tangent to the circle at point S, . Also, . Then is a straight line.
, so . This is false based on the diagram.
We have . From . .
Then using the alternate segment theorem. So .
.
Then is tangent to circle at .
Let .
In triangle
So,
Then
So
In triangle , by the tangent to the radius. So .
Then .
.
.
We use the theorem that the angle between the tangent and the chord equals the angle in the alternate segment. . Also, the angle sum in a triangle is .
(A) . .
In ,
The angle sum in a triangle is so,
Angle .
. So,
.
(A) .
(B) .
