Answer:
7)
to work it out:
180-110= 70
because there are two unknown angle we're gonna assume they're both the same amount. So if they are both the same and equal then we need to half 70 which will be equal to the two sided. So. 70/2= 35
So the 2 x's = 35 each
8)
you need to put this all into an equation so:
7x-11 + 5x-2 + 2x-3 = 180 degrees
12x - 9 + 2x-3
10x + 6
Actual answer:
14x-16
