Question

in the given figure find x and y and then show that l ll m​

Answer 1

x = 50° [ angle vertical Opposite to angle of 50° ]

130° + y° = 180° [ Linear Pair ]

y = 180° - 130°

y = 50°

Since x = 50° and y = 50° ,

•°• x = y

Hence, l and m parallel because alternate interior angles of parallel lines which are intersected by a transversal are equal

Hence, Proved
