Asked by Landon

Brittany uses a board to form a walking plank across a small ditch that has uneven sides. The board is 6 feet in length and stretches across the entire ditch. The higher side of the ditch is 3 feet above the other side. Using the inverse sine, what is the approximate angle of elevation formed between the board and the lower side of the ditch?(1 point)5°.008°60°30°

The vertical rise is 3 ft and the board is the hypotenuse 6 ft, so sin(theta) = 3/6 = 1/2. Thus theta = arcsin(1/2) = 30°.
