Answer:

The height of the building is 0.23mi

Explanation:

Hello,

To find the height of the building, we have to relate the distance between the building and the angle of elevation.

This would give us a right angle triangle with 13°.

See attached document for better illustration.

Assuming the height of the building is h,

Using SOHCAHTOA

Tanθ = opposite/adjacent

θ = 13°

Opposite = h

Adjacent = 1mi

Tan13 = h / 1

h = 1×tan13

h = 1 × 0.23

The height of the building is 0.23mi
