Answer:
1. If you draw LMN in the first quadrant of the coordinate plane ( meaning if you draw where both x and y are positive), you will end up drawing L'M'N' in the third quadrant(where both x and y are negative) because the transformation rule of a 180° rotation is (x,y)→ (-x,-y). So for example, if L is (2,3), then, by the 180° rotation rule, L' would be (-2,-3) and that would apply to all the points.
2. When you draw a line through points L and L' or M and M' they create a straight line. In other words, they create a 180° angle. And yes, you would notice the same characteristic if you drew another line that goes through points N and N', and I know this because we use a 180° rotation, so it is going to create a 180° angle, which is a straight line. Another example is if we did a 90° rotation, when we connect points A and A' for example, it would create a 90° angle between the two points. So it's the same in this case but with a 180° rotation.
Step-by-step explanation: the explanation is on the answer.
hope this helps :)
Angle C = 47°!
The angle is half of the intercepted arc. Since the intercepted arc, AD, is 94, the angle would be 94 / 2 or 47!
Hope that helps!

Answer:
460 teens
Step-by-step explanation:
10% = 0.1
multiple 0.1 by 4600 to get the amount of teens at the game. You could also do 4600/10 = 460
Answer: It is B and C.
Step-by-step explanation:
If you divde the -4 and -5 for choice B, it will become 4/5 since it's an absolute value.
For Choice C, it's also the same but before the fractions were negative and there is a negative sign which means it's also the aboslute value which is 4/5.
Hope this helps! <3
