Question

in fig, lines xy and mn intersect each other at point o . if poy =90° and a : b = 2:3 then the value of c is a) 140° b) 120° c) 80° d) 95°​

Answer 1

Answer:

If angle POY equals to 90 degree then angle POC should be equal to 90° by linear pair

axiom. Let a be 2x and b be 3x

Then 2x+3x=90°

X=90%/5

X=18°

Therefore, b=3x=3x18°-54° If b is 54 degree then c will be equal to126°
