The triangle and the trapezoid share a 15-inch base and a height of 10 inches.
a. The area of the trapezoid is less than twice the area of the triangle. Find the values of x. Explain your reasoning.
x>
and x<
inches
I have no idea what x is, but if it is the smaller base of the trapezoid, then
trapezoid: A = (15+x)/2 * 10
triangle: A = (15+0)/2 * 10
