Answer:

2x+x = 180

3x =180

x=60

angle A=120

angle B=60

angle C=120

angle D=60

there is a equaliteral triagle

5x-8=3x+2

2x=10

x=5

AB=5.5-8

AB=17

In a parallelogram...AB= DC; & BC=DA.

SO, 3x+2 =5x-8.

2x =10 ; x= 5.

So , length of AB = 3 *5 +2 = 17 unit.

ang A = 2* ang B.

For parallelogram ang A+ ang B = 180 ; ang A= ang C & ang B = ang D.

So let ang B =x.

So, 3x =180.

x= 60.

So. Ang B = Ang D = 60.

Ang A = Ang C = 2 * 60 = 120.
