Answer 1

28.7 ft²

Explanation:

Answer 2

`A=28.7\ ft^(2)`

Explanation:

we know that

The formula to calculate the area of a triangle applying the law of sines is equal to

`A=(1)/(2)(a)(b)sin(C)`

we have

`a=14\ ft`

`b=12\ ft`

`C=20\°`

substitute in the formula

`A=(1)/(2)(14)(12)sin(20\°)`

`A=28.7\ ft^(2)`
