Answer:
x = 9
Step-by-step explanation:
x + 3 = 12
subtracting both sides by 3
x + 3 - 3 = 12 - 3
x + 0 = 9
x = 9
12 x times 8 equals 96 and 180 subtracted by 96 equals 84

Answer:
65 degrees.
Step-by-step explanation:
It's hard to explain, but I'll try:
The outside of the first two angles is 105 and 140. Half a whole angle is 180. So, you do
180-140=40. The inside is 40.
And then 180-105=75.
Then you add the two and subtract them from 180:
40+75= 115
180-115=65
Voila!
