Question

help with finding side of triangle

Answer 1

Bob is driving along a straight and level road straight toward a mountain. At some point on his trip he measures the angle of elevation to the top of the mountain and finds it to be 25°11'. Find the height of the mountain to the nearest foot if Bob is 19,427.5 feet from the center of the mountain at the base.

Answer 2

opp/adj = tan

Answer 3

what does the 11 in the 25°11' mean then

Answer 4

tan(34 40/60) = h/(x-5280)
---
Therefore 0.4748x = 0.69157(x-5280)
0.4748x = 0.69157x-0.09157*5280)
---
-0.2168x = -0.09157*5280
---
x = 2230 ft
