One angle = x
second angle = (5x+18)
third angle = 180 - (x+5x+18)
third angle = 180-(6x+18)
third angle = 180 -6x-18
third angle =

The sum of the angle of a triangle is 180〫. If one angle of a triangle measures x and the second angle measures (5x+18)〫, express the measure of the third angle in terms of x. Simplify the expression.
-----
3rd angle = 180-(x+5x+18)
= 180-6x-18
= 162-6x
