Question

A tower that is 30m tall casts a shadow 75m long. Find the angle of elevation of the sun​

Answer 1

Answer:

tanx = 2/5

Step-by-step explanation:

Consider a right angled triangle ABC where the vertical side is the tower and the horizontal side is the shadow cast by it .

AB = 30 m

BC = 75 m

Let angle C be x

tan x = opp/adj = AB/BC = 30/75 = 10/25 = 2/5

$x = angle \: of \: elevation = {tan}^{ - 1} ( \frac{2}{5} )$
