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