Question

In picture ,if PQ||Rs and QR||TS,then find the value of A.​

Answer 1

Here PQ||RS and QR||TS.

Angle RQP = Angle QRS = 85° (By alternate interior angle)(PQ||RS)

Now Angle QRS = Angle TSR = 85° (By alternate interior angle)(QR||TS)

Now Angle TSR + Angle a = 180 degree( Linear pair.)

Therefore a = 95 degree.

Hope it helps.
