if the measure of angle 3 is equal to 4x+18 and the measure of angle 5 is equal to 6x +2 find the measure of x that proves line AB is parallel to line cd​

Sagot :

Answer: x=8

Solution:

<3=4x+18

<5=6x+2

<3 =<5

4x+18=6x+2

4x-6x=2-18

-2x=-16

-2x/-2=-16/-2

x=8

#CHECK FIRST, SUBSTITUTE X BY 8

#IF X=8

<5=4x+18

<5=4(8)+18

<5=32+18

<5=50

<3=6x+2

<3=6(8)+2

<3=48+2

<3=50
