Question

∠LMN and ∠NMO are a linear pair of angles. If ∠LMN = 4x + 3 and ∠NMO = 10x – 5, then find the value of x. (1 point)
x = 10
x = 12
x = 14
x = 13

Answer 1

Linear angles add up to 180 degrees.
4x + 3 + 10x - 5 = 180 -- combine like terms
14x - 2 = 180 -- add 2 to both sides
14x = 182 -- divide by 14
x = 182/14
x = 13
