The exterior angle of a triangle is equal to the sum of the other 2 oposite interior angles
therfor
95=4x-8+3x-18
95=7x-24
add 24 both sides
119=7x
divide both sides by 7
17=x
sub back
4x-8
4(17)-8
68-8
60=∠F
3x-16
3(17)-16
51-16
35=∠G
The simple interest would be $210. I hope that helps!
4(2x-7)=8x-28
4(-4x+18)=-16x+72
(8x-28)-(-16x+73)
24x+45
3(6)+8=26
I think 26 is the answer
