Question

Question is down below. Please explain throughly why the answer is correct.

Answer 1

We have that the hypotenuse is 5.2 feet and we wish to find the angle Θ, therefore:

`\begin{gathered} \cos \theta=(BD)/(AB) \\ \cos \theta=(3)/(5.2) \\ \theta=\cos ^(-1)((3)/(5.2)) \\ \theta=54.77\approx54.8 \end{gathered}`

Answer: 54.8°
