Question

The area of triangle ABC is 1.89 square feet. The measure of side c is ______.

Answer 1

Answer:2.1

Explanation:

Answer 2

we are given

Area is 1.89

`A=40`

`b=2.8`

now, we can use area formula

`A=(1)/(2) c*b*sin(A)`

`1.89=(1)/(2) *c*2.8*sin(40)`

now, we can solve for c

we will get

`c=2.10023`.............Answer
