Answer:

x=8

Step-by-step explanation:

Since this is  an isosceles triangle, the angles in the triangle are 4x, 4x, and 84.  The sum of the three angles in a triangle are 180.

4x+4x+ 84 = 180

Combine like terms

8x+84 = 180

Subtract 84 from each side

8x+84-84 = 180 - 84

8x = 96

Divide each side by 8

8x/8 = 96/12

x = 8

PtichkaEL [24]
Hey once again ! 

I will explain you how to get the answer...

What I did is multiply $21,500 times 30 = $645,000
Then I multiplied $65,470 times 30 = $<span>1,964,100</span> 

After I had multiplied, I subtracted the results.

$645,000 - $1,964,100 = $1,319,100

So the difference is $1,319,100 

I hope I was able to help you out ! :D

0.40x < = 5.10 - 1.90
0.40x < = 3.20
