The volume of a triangular prism is 70 cubic inches. The base of the prism is a right triangle with one leg whose measure is 5 inches. If the height of the prism is 4 inches, determine and state the length, in inches, of the other leg of the triangle.
What is 7 cubic inches?
These angles are formed when two parallel lines are cut by a transversal, and they lie on opposite sides of the transversal but inside the parallel lines.
What are alternate interior angles?
