The correct statement which is true about angle 3 and 5 is, they are supplementary.
Step-by-step explanation:
- Two parallel lines are intersected by a third line so that angles 1 and 5 are congruent as they are supplementary.
- Supplementary Angles are Supplementary when the two angles are add up to 180 degrees.
- Examples of supplementary angles are 60° and 120°.
- Two lines are parallel when their slopes are equal. In order to see if the two lines are parallel, we must compare their slopes.
- A transversal is also known as a line segment, that intersects two or more other lines or also a line segments. When a transversal intersects parallel lines many angles are formed, which are known as congruent.
- If two parallel lines are intersected by a transversal, the corresponding angles are congruent.
- If two lines are intersected by a transversal, the corresponding angles are called as congruent i.e the lines are parallel.

Answer:
A) 3.5
B) 15cm
Step-by-step explanation:
Part A:
length of rec2/length of rec1 = 21/6 = 3.5
Part B:
breadth of rec2/scale = 52.5/3.5 = 15cm
The perimeter would be 24 units.
Let L be the length and w be the width of each tile.
The perimeter is given by 2L+2w; we know this is 12, so we have the equaiton
2L+2w=12.
Placing two of thee tiles together changes the perimeter to 18. Assuming we place one tile above the other, so that the length of two of them is in the middle, we have 4 w's and 2 L's on the outside of the tile; this gives the equation
4w+2L=18
(Side note: this will work the same way, with the same answers, if you place the tiles beside each other instead of one atop the other.)
This makes our system of equations
2w+2L=12
4w+2L=18
Since the coefficients of L are the same, we can eliminate the L's by subtracting:
(2w+2L=12)-(4w+2L=18)
2w-4w+2L-2L=12-18
-2w=-6
Divide both sides by -2:
-2w/-2=-6/-2
w=3
Substituting this into the first equation,
2L+2(3)=12
2L+6=12
Subtract both sides by 6:
2L+6-6=12-6
2L=6
Divide both sides by 2:
2L/2=6/2
L=3
This means that each tile is a 3 by 3 square.
If we arrange 4 of these to form a square, this would be 2 rows and 2 columns.
This means we would have 3+3=6 for each side of the square, and the perimeter would be 4(6)=24.
