Question

Answer fast with full explanation pls​

Answer 1

Answer:

a=40 and b=55

Step-by-step explanation:

a is 40 as they are alternate interior angles

and b is 55 because they are also in alternate interior angles

Answer 2

Answer:

in ∆EDC we have

angle E = 55

angle D=40

therefore angle C =

angle E+ angle D + angle C=180

because angle sum property of a triangle

therefore angle C = 180-( 55+ 40)

=180-95

=85

also in triangle ABC we have angle C = angle C of triangle EDC

therefore angle C =85 because vertically opposite angles

angle A = 40

and angle b would be 55
