Calculate 43331

From the lookout tower, 70 meters high, we see a man at a depth angle of 15 degrees. Calculate how far one stands from the base of the lookout tower. Draw and calculate.

Correct answer:

x =  261.2436 m

Step-by-step explanation:

h=70 m α=15   tan α = h:x  x=h/tanα=h/tan15° =70/tan15° =70/0.267949=261.244=261.2436 m
