So this is a coordinate system so put it into y=mx+b format so 3y+2y=19 3y=19-2x Y=(-2x+19)/3 Y=-2/3x+19/3 19/3=6 and 1/3 So y=-2/3x+19/3 Put in values for x and y and get answers exg If you put in 3 For x then Y=-2+19/3 19/3=6 and1/3 -2+6 and 1/3=4 and 1/3 X=3 and y=4 and 1/3 (or 13/3)

spayn [35]

Answer:

Q.5 ab=cd

Q.6 ad=bc

Q.7 ce=ae

Q.8 eb=ed

Q.9 angle D=angle B (opposite angle of parallelogram are equal)

let other angle of parallelogram be x.

angle A+angle B +angle C + angle D= 360° (sum of quadrilateral is 360°)

x+130°+x+130°=360°

2x+260°=360°

2x=360°-260°

2x=100°

x=100/2

x=50°

Q.10 similarly, angle b= angle d

let other angle be x.

x+61°+ x+61°=360°

2x+122°=360°

2x=360°+122°

2x=238°

x=238°/2

x=119°

Q.11 in quadrilateral opposite angles are equal and opposite angle of parallelogram are equal.

Q.12 in quadrilateral opposite angle are equal and opposite angle of parallelogram are equal.

Q.13 in quadrilateral opposite sides are equal and opposite sides are parellel and this property is also present in parallelogram.
