Answer:
18
Explanation:
The equation would be :
The straight line has an angle of 180. So all of the angles together would equal 180. We add 2w + 5 twice because we are told that angle 1 and 2 equal each other and we are given one of the angles. They tell us the told of angles 3 and 4.
6w -10 +2w + 5 + 2w +5 = 180 Combine like terms
10w = 180 Divide both sides of the equation by 10
w = 18
