Pls mark me brainliest

Step-by-step explanation:

1 ) Parallelogram - Diagonals of a parallelogram bisect each other

6y-1= 5y+1

6y-5y=1+1

y =2

3x-1= 2(x+1)

3x-1= 2x+2

3x-2x=2+1

x= 3

2) Rhombus - A Rhombus has all the sides equal.

The diagonals of rhombus bisect other at right angles.

X=90-40=50degrees

y= 40 degrees (base angles of isosceles triangle are sell equal).
