Question

Please answer the above question with explanation.​

Answer 1

Step-by-step explanation:

angle B =Angle A+angle C

=60+20

=80°

angleB+angle D=180°

80+angle D=180°

angleD=100°

Answer 2

Angle B = 100° ( angle sum property

60 + 20 + x = 180

180-80=100°

In other triangle

Angle A = 20 because alternate interior

Angle C = 60 because alternate interior

Angle D = 100° because angle sum property.
