Two boats

Two boats are located from a height of 150m above the surface of the lake at depth angles of 57° and 39°. Find the distance of both boats if the sighting device and both ships are in a plane perpendicular to the surface of the lake.

Correct result:

x =  109.5121 m

Solution:

h=150 m A=57  B=39   x1=h tanA=h tan57 =150 tan57 =150 1.539865=230.97974 x2=h tanB=h tan39 =150 tan39 =150 0.809784=121.4676  x=x1x2=230.9797121.4676=109.5121 m
