Observation 76644

From the smaller observation tower, we see the top of the larger tower at an elevation angle of 23°, and the difference in their heights is 12 m. How far apart are the observation towers?

Correct answer:

x =  28.27 m

Step-by-step explanation:

α=23  y=12 m  tan α = y:x  x=y/tanα=y/tan23° =12/tan23° =12/0.424475=28.27=28.27 m
