Find the perimeter of the
Answer to Problem 2STP
G
Explanation of Solution
Given:
Triangle RST is circumscribed about the
Formula Used:
If two tangent segments are drawn from the same external point , then the two segments are equal.
Calculation:
Since the two tangent segments drawn from same point R to the circle, they are equal:
Since the two tangent segments drawn from same external point T to the circle, they are equal:
So, the perimeter of the triangle RST is :
So, the correct option is G.
