Answer: for the first one it is the ll because on the first one it measures 80 degrees for both angles and so for the the second just that it's 90 degrees
For the second 2 questions the are parallel because they don't join together but go straight until infinite.

Answer:
(3,0,0)
Step-by-step explanation:
3x + 5y + z = 9 --------------(I)
-4y - z = 0 -------------------(II)
z = -4y
2x + 3y - 4z = 6 (III)
Substitute z = -4y in equation (I) and (III)
3x +5y - 4y = 9
3x + y = 9 -----------------------(a)
2x + 3y - 4*(-4y) = 6
2x + 3y + 16y = 6
2x + 19y = 6 -------------------(b)
Multiply equation (a) by (-19) and then add. So, y will be eliminated and we can get the value of x
(a)*(-19) -57x - 19y = -171
(b) <u> 2x + 19y = 6 </u>
-55x = -165
x = -165/-55
x = 3
Plugin x = 3 in equation (a)
3*3 + y = 9
9 + y = 9
y = 9 - 9
y = 0
Plug in y = 0 in equation (II)
-4*0 - z = 0
z = 0
Answer:
196 patches
Step-by-step explanation:
We are told that the quilt is made out of square pieces that have a perimeter of 24 square inches.
This means that, length of one side = 24/4 = 6 inches.
Now since Morgan is making a square quilt with an area of 49 square feet for her nephew, let's convert 6 inches to ft.
6 inches = 6 × 1/12 = 0.5 ft
Thus, the area of a small quilt = 0.5 × 0.5 = 0.25 ft²
Number of patches = 49/0.25 = 196 patches
