Question

from a point 50 m from the base of a cliff, a surveyor measures the angle of elevation to the top of the cliff as 73.2 degrees. how tall is the cliff to the nearest metre.

Answer 1

tan 73.2 = h/50
so
h = 50 tan 73.2

Answer 2

Tan 73.2 = h/50
Bring 50 onto the left side
50 Tan 73.2 = h
165.6 = h
Round it to closest decimal place
166 = h
