Question

A ramp 19 ft long rises to a platform that is 14 ft off the ground. Find X, the angle of elevation of the ramp, Round your answer to the nearest tenth of a degree,

Answer 1

Using Pythagoras theorem

`\begin{gathered} \sin x\text{ = }(opp)/(hyp) \\ \sin x\text{ =}(14ft)/(19ft) \\ \sin x\text{ = 0.7368} \\ x\text{ = }\sin ^(-1)\text{ 0.7368} \\ x=47.46^0 \end{gathered}`

Hence the value of x = 47.5°
