Question

Q.12. In the given figure, PQǁ RS, ∠ABC= 60° and ∠ACS= 100°, find the measure of ∠BAC and ∠ ACB

Answer 1

Answer:

∠ACB = 80°

∠BAC = 40°

Step-by-step explanation:

∠ACS + ∠ACB = 180°

∠ACB = 180° - ∠ACS

∠ACB = 180° - 100

∠ACB = 80°

∠ABC + ∠BAC + ∠BCA = 180°

∠BAC = 180° - ∠ABC - ∠BCA

∠BAC = 180° - 60° -80°

∠BAC = 40°
