Answer:
D. 90tan50 degrees
Step-by-step explanation:
The tree is known as the opposite leg of the 50 degree angle, and the given 90 feet is the adjacent leg. Here, we use tan because SOHCAHTOA can help us remember tan means opposite over adjacent. Then, we do tan50 degrees = (the height of the tree)/90. To solve, multiply tan50 by 90. This gives us the height of the tree = 90tan50 degrees.
