Answer :
Answer:
60
Step-by-step explanation:
A straight line is 180 degrees
180 = (x+126) - (x+66)
180-126-66 = -12 = 2x
x = -12/2 = -6
x+66 = -6+66 = 60
Hope this helps!
Answer:
x + 66 = 60°
Step-by-step explanation:
x + 66 and x + 126 are same- side interior angles and sum to 180°
sum the 2 angles, equate to 180 and solve for x
x + 66 + x + 126 = 180
2x + 192 = 180 ← subtract 192 from both sides
2x = - 12 ← divide both sides by 2
x = - 6
Then
x + 66 = - 6 + 66 = 60°
