Angles A  and C  are supplementary     And B and D  are supplementary [sum to 180 degrees ]

 

So we have

 

(x + 2)  + ( x - 2)  =180

 

2x  = 180     divide both sides by 2

 

x  = 90

 

So  A  =   90 + 2 = 92 degrees

C  =  90 - 2  =  88 degrees

D  = 90  - 10  =  80 degrees

And  B = 180  - D   =  180  - 80  = 100 degrees
