Question

Find the area of the triangle described below. Round to the nearest hundredth.C = 43°, b = 21, a = 28

Answer 1

Recall the Formula

`\text{Area}=(1)/(2)ab\text{ sin}C`

Given

C = 43°, b = 21, a = 28

`\begin{gathered} \text{Area}=(1)/(2)*28*21*\sin 43 \\ \text{Area}=200.5075 \end{gathered}`

The final answer

`\text{Area}=200.5075unit^2`
