Question

I Need help answering this question pls help what is the measurements.

Answer 1

21 degrees.

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,

`5u = 105`

To find m1 which is 1 unit, we basically divide 105 by 5.

`105 / 5 = 21`

Angle m1 is 21 degrees.
