Question

Can someone help? Thanks a lot!!

Answer 1

x = 4

Explanation:

6x + 42 and 18x - 6 are alternate angles and are congruent , so

18x - 6 = 6x + 42 ( subtract 6x from both sides )

12x - 6 = 42 ( add 6 to both sides )

12x = 48 ( divide both sides by 12 )

x = 4

Answer 2

6x+42+18x-6=180
24x+36=180
180-36=24x=144
X=6
