You are standing 25 ft from the foot of a tree. The angle of elevation as you look at the top of the tree is 320. How tall is the tree that you are looking at?

 15.62 feet

Step-by-step explanation:

First, draw a picture (see attachment). Then, use trigonometry to solve.

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
