Question

Find the value of x. Round to the nearest tenth. What does x equal?

Answer 1

x = 8.5

EXPLANATION :

Using sine law :

`(\sin A)/(a)=(\sin C)/(c)`

A = 28 degrees

a = x

C = 83 degrees

c = 18

The value of x will be :

`\begin{gathered} (\sin28)/(x)=(\sin83)/(18) \\ \\ \text{ Cross multiply :} \\ \\ 18\sin28=x\sin83 \\ \\ x=(18\sin28)/(\sin83)=8.51\sim8.5 \end{gathered}`
