The rectangle can be drawn as follows:

The angle we are to find is labelled θ.

Considering ΔDBC, we can use the Tangent Trigonometric Ratio to get the angle:


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

Therefore, we can substitute as follows:


\begin{gathered} \tan \theta=(6)/(8) \\ \tan \theta=0.75 \\ \theta=\tan ^(-1)0.75 \\ \theta=36.9\approx37^(\circ) \end{gathered}

Therefore, the angle is 37°
