a triangular prism has a surface area of 500 square feet, a length of 15 feet, a height of 10 feet, and sides of 5 feet. find the length of the base (width) of the triangular prism. use the proper equation. you will enter the width (base) as "x". then solve for x.

Cot(90° − x) = 1 the value of x that satisfies this equation is °. a. 60 b. 135 c. 225 d. 315
