Question

in this figure L and M are parallel lines. find the values of A and B , if the transversals cutting them are not parallel

Answer 1

Let us calculate A first.

Considering L ║ M, we get,

Angle A + 125° = 180° ( Alternate interior angles )

=> Angle A = 180° - 125° = 55°

Now let us calculate Angle B.

Considering L ║ M, we get,

Angle B + 110° = 180° ( Alternate Interior angles )

=> Angle B = 180° - 110°

=> Angle B = 70°

Therefore Angle A = 55° and Angle B = 70°

Hope it helped !

Answer 2

a= 55

b= 70.
