Question

I really need help:(

Answer 1

Answer: the height of the building is 40ft

Step-by-step explanation:

Looking at the right angle triangle formed,

With angle P as the reference angle, the length shadow of the building on ground represents the adjacent side of the right angle triangle.

The height of the building represents the opposite side of the right angle triangle.

a) to determine the height of the building, x, we would apply the tangent trigonometric ratio which is expressed as

Tan θ, = opposite side/adjacent side. Therefore, the equation becomes

Tan P = x/50

b) 0.8 = x/50

x = 50 × 0.8

x = 40 ft
