Question

What is the measurement of m<2. please explain.​
​

Answer 1

Answer : 39

Explanation:

Since angles 3 and 4 are supplementary, the add up to 180.

3 + 4 = 180

Substitute the 4 for 81

3 + 81 = 180

Simplify

3 = 99

So, a triangle’s angles add up to 180

1 + 2 + 3 = 180

Substitute 1 and 3 in

42 + 2 + 99 = 180

2 = 39
