m < 1 = 130°
m < 1 = 130°m < 2 = 50°
We know this is a linear pair, therefore the two angles must add up to 180°


Combine like terms

Isolate the variable


Plug in 26 for x in both of the individual angle equations.






A good way to check if we did this correctly, is to add up the two angles. Because 180 + 50 = 180, we did this correctly.
