Question

please tell the right answer​

Answer 1

Answer:

155,  50

Step-by-step explanation:

as l || m || n

a+25 = 180 (Corresponding angles are supplementary)(OM is transversal)

∴ a = 155 degrees

∠PQO = ∠QOR (Alternate interior angles)(QO is transversal)

∴∠ QOR = 75 degrees

∠b + ∠MOR = 75

b + 25 = 75

∴ b = 50 degrees
