Answer:
m<2 = 150
Step-by-step explanation:
m<2 = 150 because of alternate exterior angles
I believe it might be 107.9 after if that’s what your asking-like taking off 10% of $108.
The data is a little bit complex,but you can use the knowledge of vector in the subject of algebra,or you can ultimate the basic Euclidean knowledge,like cosine theorem.In detail,you can list two equation with two variable,and get the answer.but i don't finish calculating it.
2m+3=23
2m=20
m=10
let me know in the comments if you need further explanation :)
