You have a composite figure that has 1 semi-circle, 1 rectangle, and 1 triangle. The height of the side shared by the rectangle and semi-circle is 4, and the height of the triangle is the same. The length of the rectangle to triangle is 10. If the length of the rectangle is 6 how would you find the base of the triangle?
You would find the base by subtracting 6 (the length of the rectangle) from 10 (the total length of the rectangle and triangle)
