If he descends 60.5 feet from the top of the reef, then the elevation to the top of the reef is 60.5 feet
Just substitute the first equation into the second and solve for x: <span><span>32</span>x=−<span>12</span>x+4⟹2x=4⟹x=2</span><span>Now, since y = 3/2 * x, we have y = 3 and we are done.</span>
26^2 = 18.8^2 + H^2
H^2 = 322.56
H = 17.96 inches
