Answer:
The inequality for w is 2
Answer:
in
Step-by-step explanation:
First you must set up an equation. 
Then, you must solve for x. 
I don’t think so but it’s hard to tell without the numbers on the chart
<2 and <3 are supplementary angles...therefore they must equal 180°
since <2 = 125
you can find the measure of <3 by subtracting the measure of <2 from 180°
180 - 125 = 55° < answer
hope this helps :)
