An engineer on the ground is looking at the top of a building. The angle of elevation to the top of a building is 38º. The engineer knows the building is 300 ft tall. What is the distance from the engineer to the base of the building to the nearest whole foot?

A) 234 ft

B) 487 ft

C) 185 ft

D) 384 ft

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
