Answer to Problem 3MRE
The number of point of intersection for a triangle circumscribed about a circle is 3
Explanation of Solution
Side of triangle will act as tangent of any circle inside triangle. Tangent of circle as side will have one point of tangency. Thus, all three sides of triangle must have tree point of tangency.
Hence, the number of point of intersection for a triangle circumscribed about a circle is 3 as shown below:
Here, D, E and F are the point of intersections.

Mariela’s line of sight to the top of the tree creates a 42° angle of elevation, and her line of sight to the base of the tree creates a 31° angle of depression. What is the height of the tree, rounded to the nearest foot? Be sure to show your work to explain how you got your answer.arrow_forward
