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
(x + 3) ( x + 1 )
because 3 x 1 = 3 and 3 + 1 = 4 , which gives you 4x.
The fractions would be in order-
3/10, 1/2, 4/5
Because if you change each fraction to a denominator of 10, the numbers will be 3/10, 5/10, and 8/10
Ax - b = c....subtract ax from both sides
-b = -ax + c <==
or it could also have been b = ax - c (but that ones not there)
