Question

1. For each parallelogram, find the values of 'x', 'y', and 'z'.
​

Answer 1

Answer:

z° = 120° [ opposite angles of parallelogram are equal ]

y° = 30 ° [ alternate angles as opposite sides of parallelogram ]

x° = 180°- ( z+y ) [angle sum property of triangle ]

x° = 180°-(120°+30°) = 180°-150°

x° = 30°

Answer 2

Answer:

x=30degree

y=120degree

z=30 degree

Step-by-step explanation:

we know that in parallelogram opposite angles are equal

so, z=120 degree

and also addition of adjacent angle is 180 degree

so, 120+30+x=180

Or, x=30

similarly y=30degree
