Answer:
-2
Step-by-step explanation:
Add 5 to both sides to get
3x-5+5=-11+5
and simplify to get
3x = -6
x = -2
Answer:3-
It's going to be negitive
B. y = x + 1
68
m7 + m8 = Straight line = 180
So, m7 = 180 - 112 = 68
AB+BC+AC=180°
8 - 7 + 2x +3x -8= 180°
-7+5x=180°
x=180°+7/5
x=37.4°
again
BC=-7+2*37.4
=67.8°
