Answer:
x=2
Step-by-step explanation:
Since these angles are supplementary, they together equal 180 degrees, so you can set it up like so:
149+5+13x=180
combine like terms:
(149+5)+13x=180
154+13x=180
Subtract 154 from both sides:
154(-154)+13x=180(-154)
13x=26
divide both sides by 13:
13x(/13)=26(/13)
x=2
2 is your answer
