@love_jessika15 
If a triangle is circumscribed about a circle, the sides of the triangle are tangent to the circle.

directrix · Answer

The angle at point S is formed by the intersection of two tangents to the circle from a point outside the circle.

directrix · Answer

To get its measure, use the formula for that ilk of angle.
