Question 754878: a person starts out 17 miles from the base of a tall mountain and looks up at a 4 angle of elevation to the top of the mountain. when he moves 12 miles closer to the base of the mountain what will be his angle of elevation when he looks to the top Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! Trigonometric ratios
Tan(4)degrees = opposite/17
Opposite = tan(4) x 17 = 1.2
He moves 12miles closer, so 5 miles from mountain
Using tan = opposite/adjacent
tan = 1.2/5
tan = 0.24
tan^-1 = 13.5 degrees
Hope this helps
