Question

find value of unknown angles​

Answer 1

x+50=90

x = 90-50

× = 40

X=Y ( it is common )

so Y=40

Z+Y=90

Z=90-40

Z=50

Answer 2

Hey mate here is your answer.

as you know sum of all angles of a parallelogram=360°.

1 angle is 50°. so its opposite angle is also 50°.

2 ,3 angle that is x,y  are unknown angles ,

so use this formula:  

x and y are equal :

50+50+x+y=360,

100+x+y=360,

take y also as x,

100+x+x=360,

100+2 x=360,

2 x= 360-100

2 x =260

x=260/2 =130

as,x=y

the value of x and y is = 130°.

now the 4 angle which is unknown is 50°

50+z=180°,

z=180-50

so the value of z  is 130°.

finally the value of x.y.z = 130°.
