Question

in each case of the following figure BA is parallel to CD find the angles a, b, c​

Answer 1

Step-by-step explanation:

angle c = -(angle A +angle B)+180

= -(70+60) +180

=180-130 =50

now angle BAC =angle ACD

= 70

and similarly angle DCE = 180-(angle c+angle b)

=180-(50+70)

=180-120. =60
