Question

In a parallelogram abcd abc and acb are complementary then find angle acd

Answer 1

Answer:

∠ACD = 90°

Step-by-step explanation:

In a parallelogram abcd abc and acb are complementary then find angle acd

in a Parallelogram any two adjacent angles are supplementary

=> ∠ABC + ∠BCD = 180°

∠BCD = ∠ACB + ∠ACD

Putting this in earlier

=> ∠ABC + ∠ACB + ∠ACD = 180°

given ∠ABC and ∠ACB are complementary

=> ∠ABC + ∠ACB = 90°

putting this

90° + ∠ACD = 180°

=> ∠ACD = 90°
