Question

I need help. I am trying to solve problem, but I keep missing a step process

Answer 1

Answer

x = 17.6 m

Explanation

In a right-angle triangle, the side opposite the right angle is the Hypotenuse, the side opposite the given angle that is non-right angle is the Opposite and the remaining side is the Adjacent.

For this question,

Hypotenuse = 18 m

Opposite = ?

Adjacent = x = ?

Angle = 12°

So, using trignometric relations, we know that CAH means that

Cos 12° = (Adj/Hyp)

Cos 12° = (x/18)

Cos 12° = 0.9781

Cos 12° = (x/18)

0.9781 = (x/18)

Cross multiply

x = 18 (0.9781)

x = 17.6 m

Hope this Helps!!!
