Answer:

C. 139 ft

Step-by-step explanation:

Height of the pole = x + 4 ft

First, find x using trigonometric function.

Reference angle = 44°

Opposite side length = x

Adjacent side length = 140 ft

Apply TOA, which is:

Tan 44 = opp/adj

Tan 44 = x/140

Multiply both sides by 140

140 × Tan 44 = x

135.196428 = x

x ≈ 135 ft

✔️Height of the pole = x + 4 ft = 135 + 4 = 139 ft
