The method to estimate the segments when two secants intersect in the exterior of a

Explanation of Solution
The product of one secant and its external secant segment is given by the product of other secant and external secant when two segment secant intersect in the circle’s exterior.
The tangent’s square is given by the product of the secant and external secant measure when a tangent and a secant intersect on the circle’s exterior.

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
