<h3>Answer: (6,4) and (5,5). Choice C.</h3>
===========================================================
Explanation:
Check out the diagram below for a visual.
The line x = 2 is a vertical line in which every point on this line has x coordinate 2. Two points on this line are (2,0) and (2,1).
The point (-2,4) is 4 units away in the horizontal direction from the line x = 2. Basically we start at (-2,4) and move 4 units to the right to arrive at (2,4). Move 4 more units to arrive at (6,4).
In short: we reflect (-2,4) over the line x = 2 and it lands on (6,4)
We see that choice C must be the answer as no other answer choices have (6,4). So if you are pressed for time, you can stop here.
-------------
Let's keep going for the sake of completeness
We'll follow the same steps for the point (-1,5).
Move 3 units to the right to go from (-1,5) to (2,5). The goal again is to reach the vertical line x = 2
Then move another 3 units to the right to arrive at (5,5)
(-1,5) reflects over x = 2 to land on (5,5).

The given sides are 12 cm, 15 cm and 21 cm
Shortest side is 12 cm
As given that in real the shortest side is 200 m
So 12 cm=200 m
then 1 cm =
Hence 15 cm = m
21 cm = m
So,,
15 cm in the photograph is 250 m long .
21 cm in the photograph is 350 long.
Use the Pythagprean theorem:
We have:

Answer:
Option (A)
Step-by-step explanation:
By applying the theorem angle theorem in the given triangle,
Sum of exterior angle of a triangle is equal to the sum of opposite interior angles of the triangle.
Therefore, 130° = y° + y°
130° = 2y°
y =
y = 65°
Therefore, measure of interior angles 'y' of the given triangle will be 65°.
Option (A) will be the answer.
