Question

Find the value of x, y and z in the following parallelograms.​

Answer 1

Answer:

Step-by-step explanation:

y=40 degree(alternate angle)

z+y=80 degree -->z=40 degree

and x=100 degree (as opp angle are equal)

Answer 2

y = 40° [Opposite interior angles]

angle adjacent to 80° = 180°-80° = 100° [Linear Pair]

then, x = 100° [Opposite angles in a parallelogram are equal]

now, z+40+100°= 180° [Adjacent Angles in a parallelogram are supplementary]

z = 180°-100°-40°

z = 40°
