Given data:

The given right angle triangle.

The expression for tan(D) is,


\tan (D)=(BC)/(DC)

Substitute the given values in the above expression.


\begin{gathered} \tan (D)=\frac{25\text{ ft}}{45\text{ ft}} \\ D=\tan ^(-1)((25)/(45))^{} \\ =29.05^(\circ) \end{gathered}

Thus, the value of angle D is 29.05 degrees.
