Answer:
In the figure, m∠2 = 85 and m∠12 = 78.Find the measure of each angle.
1. ∠10 = 85
2. ∠8 =
–> ∠10 = ∠2 = 85°
Now,∠8 = ∠2 (Vertical)
∠8 = 85°
Hence,The answer is 85°
In the figure, m∠ 9 = 83 and m∠5 = 78.Find the measure of each angle.
1. ∠12
m∠9 + m∠12 = 180° [Linear Pair]
= 83 + m∠12 = 180°
= ∠12 = 180° - 83° = 97°
So,∠12 = 97°
2. ∠1
∠1 = ∠9 [Corresponding Angle]
= ∠1 = 83°
3. ∠4
∠1 + ∠4 = 180° = ∠4 = 180° - 83° = 97°
4. ∠3
∠1 = 13 [Vertically Opposite Angle] = ∠3 = 83°
5. ∠7 = ∠5 = 78 [Vertically Opposite Angle]
Step-by-step explanation:
