The base of a rectangle measures 8 feet and the altitude measures 5 feet. Find to the nearest degree, the measure of the angle that the diagonal makes with the base.

We can say that the 8 foot base is the adjacent side.

We can say that the 5 foot altitude is the opposite side.

the tangent of the base angle = 5/8 =.625

Therefore the angle equals

arc tangent (.625) = 32.005 degrees
