For 74. The structure of the supports for the hill consists of steel beams that run parallel and perpendicular to one another. The endpoints of the beam shown by BC are (0, 150) and (120, 0). The endpoints of the beam shown by AD are (0, 125) and (100, 0). Verify and explain why the two beams are parallel, a. b. If mZDAB = 125°, what is the measure of 2CBA? Justify your reasoning. %3D
