Question

Solve for x and found your answer to the nearest tenth.

Answer 1

11.1

Explanation:

To find the side measurement we have to use trig, and the trig function Cosine, or cos. We use the because cosθ=
`(adjecent)/(hypotenuse)`. So cosθ=
`(x)/(15)`, then to isolate x multiply both sides by 15. Now we have 15cos42=x, plugging this into the equation we get that x=11.1
