3x+x= 180°(straight angle)
4x= 180°
x= 180/4
x= 45°
<span />x=base price
x/10=major options package
x/50=destination charge
x+x/10+x/50=24,416
x=21,800
Substitute first Y for the second Y
So it would be x + x + 6 = -2
Then it would be 2x +6 = -2
Move the 6 over so it would be 2x =-8
Divide by 2 your answer is x = -4
It’s either B or D.. now you have 2 hopefully this helps
