Question

Solve for x. round to the nearest tenth​

Answer 1

43.1

Explanation:

We can figure this out by using a bit of simple trigonometry

Using the available values we know we have to figure out x using cos because it includes the adjacent and hypotenuse values.

"Soh Cah Toa"

Cos(x) = Adjacent / Hypotenuse

Cos(x) = 8/11

Cos(x) = 0.73

Using
`cos^(-1)` we can figure out x from the side length

x =
`cos^(-1)`(0.73)

x = 43.1 degrees (rounded)
