Each half of a drawbridge is 284 feet long. When one half of the bridge is raised, the
vertical rise is 142 feet. What is the measure of the angle, marked with an x on the
image, formed by the bridge and the horizontal? Round your answer to the nearest
degree, and enter the number only.
First, sin(x) = O/H Next, sin(x) ->> x = sin^-1(O/H) Last, x = sin^-1(142/284) = 30° 30° makes sense because this scenario of a drawbridge creates a 30-60-90 triangle.
