Question

please help me with this question

Answer 1

Step-by-step explanation:

First of all, angle "y" would be 57⁰ as it is a vertically opposite angle (V.O.A)

Then the sum of the angle "y" and that angle with 123⁰ would be 180⁰. That means that l is parallel to m since the sum of those angles is 180⁰, so it is a case of parallelism called "interior supplementary".

Answer 2

57 digory is same as y so y=to 57 digory
