Question

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

Answer 1

we are given

Area is 1.89

$A=40$

$b=2.8$

now, we can use area formula

$A=\frac{1}{2} c*b*sin(A)$

$1.89=\frac{1}{2} *c*2.8*sin(40)$

now, we can solve for c

we will get

$c=2.10023$.............Answer
