Q: Two cars are parked on opposite sides of a long tower. From the cars, the angle of elevation of the top of the tower is 30

Answer: C

Explanation:

Assume the distance between the tower and the two cars is x+y.'

[adjacent side = car-to-tower distance] [opposite side = tower height]

tan = opposite side/adjacent side

Triangle 1:

tan30° = 50/x => x = 50√3

tan45° = 50/y => y = 50

Distance between two cars = x + y = 503 + 50 = 50(3+1) = 50*2.732 = 136.5 m
