Answer:
the interior angle of a triangle = 180- 89 ( forming linear pair)
= 91°
y = 91 + 23
Y = 114° ( sum of interior angle of a triangle ls equal to its outer angle)
Answer:
114
Step-by-step explanation:
Angle A + 89 = 180 (Sum ofAngles in a straight line)
Angle A = 180 - 89 = 91
Angle B + Angle A + 23 = 180 (Sum of angles in a triangle)
Angle B + 91 + 23 = 180
Angle B = 180 - 114 = 66
Angle B + y = 180 (Sum of angles in a straight line)
66 + y = 180
y = 180 - 66 = 114
