Question

In the given figure, PQ || RS, find the value of a and b.​

Answer 1

Answer:

Step-by-step explanation:

join PR

So ORP=180-125-55

And OPR-180-110-70

As they are linaer pair..

so in triangle POR, we have two angles so we can find the third..

sum of all angles of a triangle=180

so 55+70+POR=180

POR=55

Answer 2

Answer:

join PR

so., ORP=180-110=70

As they are linear pair..

so in triangle POR, we have two angles so we can find the third ..

sum of all angles of a triangle=180

so , 55+70+POR=180

POR=55
