I would say the final answer is 40 degrees (please don't report me if I got it wrong)

Answer:

4.4 ft

Step-by-step explanation:

The model is a right triangle with the side opposite 35° being 2.5 ft and the hypotenuse being the length of board required.

let the length of board be x , then

sin35° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{2.5}{x}[/tex]

cross- multiplying gives

x × sin35° = 2.5 ( divide both sides by sin35° )

x = [tex]\frac{2.5}{sin35}[/tex] ≈ 4.4 ft ( nearest tenth )
