Answer:
w+76+w = 180
w = 52
Step-by-step explanation:
The angle between the w's is a vertical angle to 76, so it equals 76 because vertical angles are equal
w+76+w = 180 since it forms a straight line
Combine like terms
2w+76 =180
Subtract 76 from each side
2w+76-76 =180-76
2w = 104
Divide by 2
w =52
