Answer:
x=12
Step-by-step explanation:
The two angles are equal to 180 degrees, we already know that one angle is 110, so we find the difference.
180-110=70
4x+22=70
70-22=48
48/4=12
4x + 8y = 40
4x + 8(0.8) = 40
4x + 6.4 = 40
40 - 6.4 = 33.6
33.6 / 4 = x
33.6 / 4 = 8.4
The answer option 2, 8.4
B.
thanks have a good day :)
