Question

in the given fig ab parallel to cd , ab parallel to ef and bc parallel to bd .fin the values of x ,y and z​

Answer 1

Answer:

First join BE and extend CD on both sides.

x = angle DEF (alternate interior angles) = 75°

y + 63° = angleDEB ( opposite angles of a parallelogram)

y + 63 ° = 180 - 75 ° = 105°

y = 105° - 63° = 42°

angle DCB = angleCBA( alternate interior angles)

z = y + 63° = 42° + 63° = 105°

Answer 2

Answer:

x=75degree

y=42degree

z=105degree
