Answer:
430
Step-by-step explanation:
Use PEMDAS.

M< 6 = m< 7 (vertical angles)
11x + 8 = <span>12x – 4
12x - 11x = 8 + 4
x = 12
so
m< 6 = </span>11x + 8
m< 6 = 11(12) + 8
m< 6 = 132 + 8
m< 6 = 140
m<4 = 180 - m<6
m<4 = 180 - 140
m<4 = 40
answer
<span>m<4 = 40</span>
This should be correct I am sorry if it is not.

The numbers are 16 and 4
Reason: 16+4=20 and (16*3)-(4*2)=48-8=40
