XY=WZ=28. (Opposite sides of a parallelogram are equal)
Angle Z=angle C=105
=>angle Y=180-105=75. (Co-interior angles are supplementary)
Hope this helps u...!!
Answer:

Step-by-step explanation:
let x = 0.616161 (etc.)
make a second equation because you multiply by 100:
100x = 61.616161 (etc.)
subtract from each other
100x = 61.616161
x = 0.616161
you get
99x = 61
solve for x

B. the line is going up so it’s going to be positive not negative. the b value is gonna be negative 1 instead of positive because it crosses the y axis closer to -1 than it does 1
