Question

Soh Cah Toa. Solve for x and round to the nearest tenth

Someone please explain to me step by step

Answer 1

7.6=x

Explanation:

We know the adjacent side to the known angle and the hypotenuse

cos 65 = adjacent / hypotenuse

cos 65 = x /18

Multiply each side by 18

18 cos 65 = x/18 * 18

18 cos 65 = x

7.607128711 =x

Rounding to the nearest tenth

7.6=x
