Step-by-step explanation:
In triangle BCD:
angle CDB+angleDCB+ angle CBD=180
LET angle CDB=1 DCB=2 CBD=3
angle1+angle +angle3=180
2x+5x+3x=180
10x=180
x=18
2x=2×18=36
3x=3×18=54
5x=5×18=90
angle 2 is equal to angle A=90 ( because opposite angles of parallelogram are equal)
angle ADB=90-36=54
angle ABD=90-54=36;
angle B=36+54=90
angle D=54+36=90
hence;
angle A ,angle b, angle C,angle D are 90 degree all
