Question

Use the triangle to answer the question.Find the value of x. Round to the nearest degree.

Answer 1

Given:

base = 16

hypotenus = 21

`\cos \theta=(base)/(hypotenus)`

Angle = x

`\begin{gathered} \cos x=(16)/(21) \\ \cos x=0.76 \\ x=\cos ^(-1)(0.76) \\ x\approx40 \end{gathered}`

The value of x is 40 degree.
