With this question! i don't understand how to get the answer : (

Ur angles are supplementary...that means they equal 180 degrees when added

4x + 16 + 2x - 22 = 180combine like terms
6x - 6 = 180...add 6 to both sides
6x = 186 ...divide both sides by 6
x = 186/6
x = 31

< 1 = 4x + 16
< 1 = 4(31) + 16
< 1 = 124 + 16
< 1 = 140

When parallel lines are cut by a transversal,
the alternate interior angles are equal
