Answer:

7. 92 degrees

I can't tell if the other questions are addition or subtraction signs

If you comment it, I will complete the problem

Step-by-step explanation:

3x+23=4x

subtract 3x from both sides

x=23

to find m<ABC, replace x with 23

4(23)

92
7. 92’ (add the degrees dot)
8. 125’( add the degrees dot)

I’m not sure about 9. & 10
