In the given figure, AB || DE. ∠A = 430 and ∠BDE = 570. The value of ∠x is ________.
75°, 50°, 55°
85°, 65°, 30°
50°, 45°, 85°
60°, 35°, 85°
It is given that the lines AB and DE are parallel.
Therefore, ∠ABD = ∠x = 57∘ (alternate interior angles)
5 + 15 + 25 + 35 + 45 + 55 + 65 + 75 + 85 + 95 = ___
The measures of the inner ∠A and inner ∠C in the given figure is
