Question

Match the statement to the correct angle. If the correct angle is not shown, match the statement to none of these.

Answer 1

`\cos x=\frac{\text{adjacent}}{\text{hypotenuse}}`
`\cos x=\frac{\sqrt[]{2}}{2}`

Therefore,

`\begin{gathered} \cos 45=\frac{1}{\sqrt[]{2}} \\ \cos 45=\frac{1}{\sqrt[]{2}}*\frac{\sqrt[]{2}}{\sqrt[]{2}}=\frac{\sqrt[]{2}}{2} \end{gathered}`

The answer is x = 45 degree's
