Right Triangle QuizSolve for x. Round your answer to the nearest tenth.25A21X=Calculator

Answer 1

In this case we need the cos function:

`\cos x=(21)/(25)=0.84`

Now we use the inverse function of cos:

`\begin{gathered} x=\cos ^(-1)0.84 \\ x=32.86 \end{gathered}`

So the angle x is 32.9 degrees
