Question

In the figure AB is parallel to CD. Find x, y and z

Answer 1

Given AB || CD

∴ Z = 42° ...[∵ Alternate interior angles]

Also y = 42° ...[vertically opposite angles]

Also x° + 63° + z° = 180°

x° + 63° + 42° = 180°

x° + 105° = 180°

x° + 105° – 105° = 180° – 105°

x° = 75°

∴ x = 75°, y = 42°, z = 42°
