You know that the sum of the interior angles in a triangle is 180
we will add all the angles,
(x+8)+(2x-8)+(3x-12)=180
x+8+2x-8+3x-12=180 8 and -8 cancel out
6x-12=180
6x=180+12
6x=192
x=192/6=32
x=32

e.g.

Answer:
46.6%
Step-by-step explanation:

Answer:
The answer would be 5.
Step-by-step explanation:
If you take away 18 from 90 would be 72.
72 - 18 =54
54 - 18 =36
36 - 18 =18
18 - 18 =0
If you count that would equal 5 .
