Question

A ramp 9m long rises to a platform. The bottom of the platform is 5m from the foot of the ramp. Find x, the angle of elevation of the ramp. Round your answer to the nearest tenth of a degree.

Answer 1

X = 56 degrees (rounded)

Explanation:

in this case we are given the hypotenuse and adjacent measurments, this means we need to us cos to find the angel

`\cos(x) = (5)/(9)`

`x = \cos^( - 1) ( (5)/(9) )`

`x = 56.2510114`
