Question

Find the area of the triangle with the given measurements.Round the solution to the nearest hundredth if necessary.A=50 degrees,b=31,c=18ft

Answer 1

`\large\boxed{A\approx213.71\ ft^2}`

Explanation:

Use the formula:

`A=(1)/(2)bc\sin A`

We have:

`b=31\ ft,\ c=18\ ft,\ m\angle A=50^o\to\sin50^o\approx0.766`

Substitute:

`A=(1)/(2)(31)(18)(0.766)\approx213.71\ ft^2`
