Finding the Measures of Angles in a Linear Pair

[bernardl]

<1 and <2 form a linear pair. If m<1 = 5x + 9 and m<2 = 3x + 11, find the measures of both angles.

Hi bernardl and welcome to MHB! :D

I've re-titled your recent threads to give them a name that accurately reflects the problem at hand.

A linear pair of angles have measures that sum to 180 degrees, so we want to solve

5x + 9 + 3x + 11 = 180

for x, then substitute that value for x into the respective expressions to find the measure of the two angles.

Whoever gave you this problem clearly expected you to know what "linear pair of angles" meant! Did you? If so it is easy to set up an equation to solve.
