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

Feliz [49]

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

Answer:

Step-by-step explanation:

K(0 , 4)

Midpoint M (3 , 3)

Let Point L(x₂ , y₂)

$Midpoint= (\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2}\\\\\\ (\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2}) = (3 , 3)\\\\\\ (\frac{0+x_{2}}{2},\frac{4+y_{2}}{2}) = ( 3 , 3)\\\\\\$

Compare x and y coordinates

$\frac{x_{2}}{2}=3 ; \frac{4+y_{2}}{2} = 3$

Cross multiply,

x₂ = 3*2 ; 4 + y₂ = 3*2

x₂ = 6 ; 4+ y₂ = 6

y₂ = 6- 4

y₂ = 2

L(6 , 2)
