Answer:
angle 8 and angle 3, and angle 3 and angle 6 are supplementary to each other so you would try to find m using 180, since supplementary means is equal to 180°
Step-by-step explanation:
its like this:
angle 3 and angle 8-
97+m=180
you subtract 97 from both sides and you'll the solution, m= 83
angle 6 and angle 3 is the exact same equation as angle 8 and 3, so its also m=83
