Your answer is correct it’s 4/33. You first have to convert the mixed number into an improper fraction. Then you’ll have 1/6/11/8 and then you will simplify the complex fraction. I hope that helps!
Problem 6a
- Angle DCB is supplementary to angle ADC and angle ABC. Reason: Adjacent angles in a parallelogram are always supplementary.
- AE = EC. Reason: The diagonals of any parallelogram always bisect each other. In other words, the diagonals cut each other in half.
- DC = AB. Reason: Opposite sides of a parallelogram are congruent.
- angle DCB = angle DAB. Reason: Opposite angles of a parallelogram are congruent.
- CD = AB. Reason: segment DC is the same as segment CD. The order of the endpoints does not matter when it comes to listing a segment. Opposite sides of a parallelogram are congruent.

Problem 6b
<h3>Answers:</h3><h3>angle L = 129</h3><h3>angle S = 51</h3><h3>angle C = 129</h3>
----------
Work Shown:
angle U = 51 (given)
angle S = angle U (Opposite angles of a parallelogram are congruent)
L+U = 180 (adjacent angles in parallelogram are supplementary)
L = 180-U
angle L = 180-51
angle L = 129
angle C = angle L (Opposite angles of a parallelogram are congruent)
angle C = 129

Problem 6c
<h3>Answers:</h3><h3>x = 33/4 = 8.25</h3><h3>y = 50</h3>
------------------
Work Shown:
TI across the top is 4x+9
NA across the bottom is 42
TI = NA since opposite sides of a parallelogram are congruent
4x+9 = 42
4x = 42-9
4x = 33
x = 33/4
x = 8.25

angle TAN = 3y
angle TIN = 150
angle TAN = angle TIN (opposite angles of parallelogram are congruent)
3y = 150
y = 150/3
y = 50
Answer:
x=2
y=−1
Step-by-step explanation:
You can multiply the second equation by 3:
{2x-3y=7
{9x+3y=15 add the two together (in columns):
11x+0=22
so that x=22/11=2
substitute this back into the first equation:
2*2-3y=7
y=-1
Answer:
ok im not sure what ur asking but the square root of 625 is 25 the square root of 196 is 14 the square root of 961 is 31 and the square root of 100 is 10 hope this helped if not im sry
