Answer:
36
Step-by-step explanation:
2x is an exterior angle
Exterior angles = the sum of the two remote (unconnected - non supplementary interior angles).
Put symbolically
<LEG = <EGF + <EFG
<EFG = 180 - 4x In this case you need to find the supplemtnt
<LEG = x + 180 - 4x
2x = 180 - 3x Add 3x to both sides
5x = 180 Divide by 5
x = 36
4x ( 2x^3-x^2-18x+15)=
4(2)x^(1+3)-4x^(1+2)-4(18)x^(1+1)+4(15)x=
8x^4-4x^3-72x^2+60x
