A telephone pole shown at the top of the next column is 60 f

A telephone pole, shown at the top of the next column, is 60 feet tall. A guy wire 85 feet long is attached from the ground to the top of the pole. Find the angle between the wire and the pole to the nearest degree. The angle between the wire and the pole is approximately degrees. (Round to the nearest degree.)

Solution

cos theta=adjacent/hypotenuse

Here adjacent=60ft

hypotenuse=85 ft

cos theta=60/85

theta=cos^-1(60/85)=45 degree
