Answer:36
Step-by-step explanation:
Opposite angles of paralellogram are equal
So,3x+3=3y
3x-3y=-3_eq 1
In parallelogram opposite sides are parallel
So,DC//AB
Angle C and Angle B will be co-interior angles and their sum will be 180 degrees
3x+3+2y-5=180
3x+2y-2=180
3x+2y=180+2
3x+2y=182_eq 2
Subtracting 1 from 2 by elimination method
3x+2y=182
3x-3y =-3
- + +
_________
5y=185
y=185/5
y=37
Put in eq 1
3x-3(37)= -3
3x-111= -3
3x= -3+111
3x=108
x=108/3
x=36
