Question

Two lines PQ and RS intersect at a point o such that angle POS+ angle ROQ=280. Find all the angle.

Answer 1

140°,140°,40°,40°.....................

Answer 2

POS = x
POS = ROQ
2x = 280°
x = 140°
Other 2 angles will be equal
Total = 360°
360° - 280° = sum of other 2 angles
80° = the sum of other 2 angles
40° is the other angle
So
POS = ROQ = 140°
POR = SOQ = 40°
