Consider the figure:
If ∠B = 50∘, ∠ACD = 120∘, then find the value of ∠A (in degrees).
___
∠A = ∠ACD - ∠B = 120∘ - 50∘ (Exterior angle property) = 70∘
If ∠A = 70∘, ∠ACD = 120∘, then find the value of ∠B (in degrees).
If ∠A = 50∘, ∠ACD = 120∘, and x = 2y, then find the value of ∠B (in degrees).
If ∠A=50∘, ∠ACD=120∘, and x=2y, then ∠B= ___ ∘.
If ∠A = 50∘, ∠B = 70∘, and x = 2y, then find the value of y (in degrees).
If ∠B = 50∘, ∠ACD = 120∘, then the value of ∠A (in degrees) is .
