Step-by-step explanation:
since we know that sum of a parallelogramall the angles is 360degree
given,
AngleB =(4x-5) degree
AngleD=(3x+10) degree
Let,
AngleC and AngleA be x
ATP,
AngleA+AngleB+AngleC+AngleD=360
or,x+(4x-5)+x+(3x+10)=360
or,(x+4x+x+3x)-5+10=360
or,9x=360
or,x=360/9
or,x=40
Therefore, Angle B is (4x-5) that is equal to (4×40-5) that is equal to (160-5) that is equal to 155 degree
And AngleC is x that equal to 40.
