A 60-yard long drawbridge has one end at ground level. The other end is initially at an incline of 5°. During one stage of the d
rawbridge's motion, the raised end is 11 yards above the ground. What is the incline of the drawbridge to the nearest hundredth
1 answer:
The drawbridge will be at an incline of 10.56 degrees. That is 5.56 degrees more than it's initial incline of 5 degrees.
If you draw a picture of this situation, you will see that you can write a sine ratio with the 11 and 60 (opposite over hypotenuse)
sin(x) = 11/60 Solve the equation for x
x = 10.56
