Parallelogram

In the parallelogram, we know one internal angle of 67°33`. Calculate the other internal angles.

Correct answer:

β =  112.45 °
γ =  67.55 °
δ =  112.45 °

Step-by-step explanation:

α=67°33′=67°+6033​°=67.55°=67.55 α+β=180  ∘ β=180−α=180−67.55=112.45∘=112°27′
γ=α=67.55=67.55∘=67°33′
γ+δ=180  ∘ δ=180−γ=180−67.55=112.45∘=112°27′
