What is the measure of ∠d ?

enter your answer as a decimal in the box. round only your final answer to the nearest hundredth.

The measure of ∠D is 29° approximately.

Step-by-step explanation:  We are given a right-angled triangle BCD, where ∠C = 90°, BC = 25 ft and CD = 45 ft.

In ΔBCD, with respect to ∠D, we have

base, b = CD = 45 ft,

perpendicular, p = BC = 25 ft

and

hypotenuse, h = BD.

Therefore, we can write

Now,

Thus, the measure of ∠D is 29° approximately.
