Question

In the figureDE,AB are parallel. AngleDEC=45 degree and angleEDC=35 . Find the value of and b

Answer 1

Hey!!

here is AB ll DE then DB and AE are transversals.

Thus a = angle D = 35° ( alternative interior angle)

Similarly b = angle E = 45° (alternative interior angle )

Hope this helps

Answer 2

a=35, b=45 by applying transversal theory.
