A. Angle 3 is a vertical angle to angle 2 which means they are the same.
Angle 3 = 76 degrees
B. Angle 6 is also the same as angle 2.
Angle 6 = 76 degrees
C. Angle 8 + angle 6 form a straight line which equals 180 degrees
Angle 8 = 180 - 76 = 104 degrees
Answer:
76° , 76° , 104°
Step-by-step explanation:
(a)
∠ 2 and ∠ 3 are vertically opposite angles and are congruent , then
∠ 3 = 76°
(b)
∠ 6 and ∠ 3 are alternate angles and are congruent , then
∠ 6 = 76°
(c)
∠ 6 and ∠ 8 are adjacent angles on a straight line and sum to 180° , then
∠ 8 = 180° - 76° = 104°
