Angle z makes a 180° angle when added to the angle of 124° in the first image, because they are on the same side of a straight line. Just subtract 124 from 180. =56 For the second picture, angle m will be the same as angle z because of the properties involved.
Let as described in the problem statement. Plugging in and gives us the equations and Since are nonzero, we divide the second equation by the first to get which means that after taking the cube root. Plugging this value for into the first equation, we now have Solving gives and our desired exponential equation is
