MATE HERE IS YOUR ANSWER

BUT MAKE SURE YOU CHOOSE MY ANSWER AS BRAINLIEST ONE!!!

Step-by-step explanation:

THE DIAGRAM IS IN THE ABOVE PICTURE

From figure: Let θ be the angle of elevation.

Given: Angle are complementary, so another angle is (90- θ)°

From right triangle CAB: tan θ = AB/AC tan θ = h/5 or h = 5tan θ ….(1)

Form another right triangle DAB:

tan (90-θ)° = AB/AD tan (90-θ)° = h/20 or h = 20 tan (90-θ)° or h = 20 cot θ …(2)

Multiply equation (1) and (2), we get h2 = 100 x tan θ x cot θ h = 10 (As tan θ = 1/cotθ)

  • Height of the tower is 10m
