Since BC=DC, you know the two missing angle measurements in triangle BCD are the same. Since you also know that the total degrees of a triangle must add up to 180 degrees, you can simply do (180-82)/2
=98/2
=49
The degree of y should equal 49
Answer:
The tub is capable of holding 32 gallons, but is only (4/7) full.
If N is the number of gallons of water in the tub then
N = (4)*(32 gallons)/7 = (128/7) gallons or 18 and (2/7) gallons or 18.286 gallons depending on how you are supposed to show your answer.

Answer:
the independent variable goes on the x-axis (the bottom, horizontal one) and the dependent variable goes on the y-axis (the left side, vertical one).
