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 class=

Respuesta :

Using Pythagoras theorem

[tex]\begin{gathered} \sin x\text{ = }\frac{opp}{hyp} \\ \sin x\text{ =}\frac{14ft}{19ft} \\ \sin x\text{ = 0.7368} \\ x\text{ = }\sin ^{-1}\text{ 0.7368} \\ x=47.46^0 \end{gathered}[/tex]

Hence the value of x = 47.5°
