Given that each quadrilateral is a parallelogram, find the missing value

Angle D=102 degrees

x= 180-102= 78 degrees (co-interior angles)

Angle A = Angle D (opposite angles in a parallelogram)

3y+6=102

=>3y=102-6

=>y=96/3

=>y=32

Angle C= Angle B (opposite angles in a parallelogram)

4z+2=78

=>4z=76

=>z= 19

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
