please answer the question guys please

Answer 1

hope it helps you out

Answer 2

3...in parallelogram opposite angles are equal and sum of adjacent angles is 180°

<A+<B=180°
8x+20°=180°
8x=160°
x=20°

<A=<D
then <D=3x-10
D=50°

4.....
AB=5cm
BC=12cm

perimeter=2(B+h)=2(5+12)=34cm

1....
SPQ=65°
RSP=??
in a parallelogram opposite angles are equal....
so RSP=65°


2....
Let PQ=x
then QR=x+3
perimeter of parallelogram=2(h+b)=2(2x+3)=4x +6

given that perimeter=70cm
70=4x+6
4x=64
x=16cm
then QR=16+3=19cm




hope it helps
