Answer:

x > -4

Step-by-step explanation:

Isolate the variable, x. Treat the greater than sign like a equal sign, in that what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 7 from both sides:

3x + 7 (-7) > -5 (-7)

3x > - 5 - 7

3x > -12

Next, isolate the variable, x, by dividing 3 from both sides:

(3x)/3 > (-12)/3

x > (-12)/3

x > -4

x > -4 is your answer.

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
