Answer:
<Ber=<kem(vertically opposite angle)
9x-17=3x+31
9x-3x=31+17
6x=48
x=48/6=8
<kem=3×8+31=55°is answer
4m +2(m+1) = 9m +5
4m +2m+2 = 9m +5
6m +2 = 9m +5
6m = 9m+3
-3m = 3
m = -1
x = -8
Step-by-step explanation:
-9 (x+2) = 54
-9x - 18 = 54
-9x = 72
Hope this helps :)
Let me know if there are any mistakes!!
times the number so 18 times 30
