Answer 1

Answer:

x =

Explanations:

The triangle shown is a right-angled triangle

The missing value can be found by using the cosine formula:

`\cos \theta\text{ = }\frac{Adjacent}{\text{Hypotenuse}}`

From the right-angled triangle shown:

`\begin{gathered} \theta=18^0 \\ \text{Adjacent = 29} \\ \text{Hypotenuse = x} \end{gathered}`
`\begin{gathered} \cos 18\text{ = }(29)/(x) \\ 0.95\text{ = }(29)/(x) \\ 0.95\text{x = 29} \\ x\text{ = }(29)/(0.95) \\ x\text{ = }30.5 \end{gathered}`
