Find the value of x that will make A||BThanks for helping. :)
Accepted Solution
A:
Answer:x = 20Step-by-step explanation:The converse of the same side exterior angles theorem states that when two same side exterior angles are supplementary, the two lines they are on are parallel.So that means that 5x + 9 and 3x + 11 are supplementary.Therefore, 5x + 9 + 3x + 11 = 180.Add like terms: 8x + 20 = 180Subtract: 8x = 160Divide: x = 20
