Can somebody help me with number 7???!!! ASAP find the area triangle to the nearest tenth

Answer 1

Solution.

We are required to find the area triangle to the nearest tenth.

Two sides of the triangle and an included angle is given

`\begin{gathered} For\text{ the triangle given, } \\ a=15m \\ \text{ b=8m} \\ \theta=108 \end{gathered}`
`Area=(1)/(2)\text{ x 15 x 8 x sin108}`
`\begin{gathered} Area=57.0623m^2 \\ Area\text{ of the triangle = 57.1m}^2(nearest\text{ tenth} \end{gathered}`
