Anything with a value of w=3.5 would be equivalent.
To solve this, we cannot have a variable on both sides, so we will subtract 12w from both sides:
12w - 27 - 12w = -34 + 14w - 12w
-27 = -34 + 2w
Now add 34 to both sides:
-27+34 = -34 + 2w + 34
7 = 2w
Divide both sides by 2:
7/2 = 2w/2
3.5 = w
Angles 1, 3, 5, and 7 are obtuse angles.
Angles 2, 4, 6, and 8 are acute angles.
1) 1 and 3 are called obtuse.
3) 1 and 7 are also obtuse.
4) 4 and 6 are acute.
5) 4 and 8 are also acute.
hopes this helps a little bit :/
I think its b because a coefficient is a number that is placed in front of a variable and the 4 is just a constant
