Answer:
m<4=104 degrees
Step-by-step explanation:
Angles 3 and 4 are both supplementary angles. They both add up to 180 degrees. So, if you know one of them then you can just do 180-measure of angle 3. 180-76=104 degrees
104
Since angle 3 is 76 , you subtract 76 from 180 . You do that because a straight line is 180 .
