Question

Kasey wants to estimate the height of a tree. Shestarts at the base of the tree and walks 40 feet awayfrom the tree. She then measures the angle ofelevation from that point to the top of the tree as 50°.Which can be used to find the height of the tree?40 cos(50)40 sin(50)O 40 tan(50)40cos(50)40sin(50)40tan(50)

Answer 1

see the attached figure to better understand the problem

In the right triangle of the figure

tan(50)=h/40

h=40*tan(50)

therefore

the answer is the third option
