Question

Find the area of the triangle with the given measurements. Round the solution to the nearest hundredth if necessary.

B = 103°, a = 12 cm, c = 22 cm

Answer 1

The area of the triangle is
`128.62\ cm^(2)`

Explanation:

we know that

Applying the law of sines

The area of a triangle is equal to

`A=(1)/(2)(a)(c)sin(B)`

substitute the values

`A=(1)/(2)(12)(22)sin(103\°)`

`A=128.62\ cm^(2)`
