Answer:
21 degrees.
Step-by-step explanation:
Let m1 be one unit. Hence, m2 will be four units.
Since m2 is four times of m1, the total number of units will be 4+1=5.
Thus,
[tex]5u = 105[/tex]
To find m1 which is 1 unit, we basically divide 105 by 5.
[tex]105 \div 5 = 21[/tex]
Angle m1 is 21 degrees.
