Question

Referring to the figure, find the missing length x. Round the answer to the nearest hundredths.

Answer 1

Using cosine function:

`\begin{gathered} \cos (\theta)=\frac{adjacent}{_{\text{ }}hypotenuse} \\ \cos (45)=(8)/(x) \\ solve_{\text{ }}for_{\text{ }}x\colon\text{ } \\ x=(8)/(\cos (45)) \\ x=8\sqrt[]{2} \\ x\approx11.31 \end{gathered}`

Answer:

x = 11.31
