Three trapezoids have the same base lengths, but different angle measures. which trapezoid has the greatest area? explain. the angle measures are: 30, 45, and 60

The area of the 3 trapezoid would be all equal because the formula of the area of the trapezoid is :
A = h (b1 + b2) / 2
since the length of the base are equal in all three trapezoid, then the angle is not part in the equation of the area so the angle of the trapezoid does not affect its area. so that is why all the three trapezoid have equal area even with different angles.
