2) Use the figure to write a two-column proof. Given: WXYZ is a parallelogram.
Prove: WXYZ is a rhombus.

based on context clues you gave i'm assuming the answer would be c.

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )

16 would be your answer

i think the answer is a.( -3, -1 )
