Answer:37
Step-by-step explanation:
180-35=145 I got the 180 because that is a straight line. I got the 35 from the angle. I subtracted them because 35 is part of the 180 and does not need to be counted. Then I set 145= to 4m-3. Then I just solved normally. It should look like this
145+3=4m-3+3
148/4=4m/4
37=m
