Answer:

pls mark as brainliest

Step-by-step explanation:

1. diagonals in a parallelogram bisect each other it means the diagonal divides the other into two equal halves

5y+1=6y-1

y=2

3x-1=2x+2

x=3

2. diagonals in a rhombus are perpendicular to each other

so let us consider the center as o

so in traiangleOSR 90+40+x=180

130+x=180

x=50

opposite angles in a rhombus are equal and the diagonals bisect

the opposite angle

so in triOQP

50+90+y=180

140+y=180

y=40

8.  here we can say x+y=70

the extrerior angle is equal to sum of the interior opposite angles

here

x+45=y+angleACD--(1)

angle B=angle Z

x+z+45=180

x+z=180-45=135--(2)

z+45+angle ACD=180

z+angleACD=135

angle ACD=135-z

sunstitute in (1)

x+45=y+135-z

x-y+z=90

y=135-90=45

x=25 from (1)

z=70
