Answer:
w = 34°
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
2w + 1 + 2w + 43 = 180 , that is
4w + 44 = 180 ( subtract 44 from both sides )
4w = 136 ( divide both sides by 4 )
w = 34
Answer: W = 34°
Use the angle sum theorem!
2w + 2w + 1 + 43 = 180
4w + 44 = 180
4w = 136
