Answer:
Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. However, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
Step-by-step explanation:
The formula for this is 2
First off,congruent triangles are triangles that are equal to another,having the same area,length of sides and angles.
Judging visually,the triangles that are congruent would be:
C and E-as they are both in smaller size.
D and F-as they are both significantly irregular.
That would left A and B:
A-it is very large in size that none other could match
B-it is the only isosceles triangle.
Thus the answer is A and B as they do not match with any others.

If the perimeter is 13y-5, then it should be equal to all of these sides added together. So, let’s add all of the sides we already know up:
5y-4 + y + 3y+1 = 9y-3.
Now set this equal to the perimeter we already know:
9y-3 = 13y-5. Subtract 9y from both sides.
-3 = 4y-5. Add 3 to both sides.
4y-2.
Now we have the value of 4y-2. Since we know that the last two sides are completely the same, then we can divide this expression by 2.
Therefore, the remaining side is 2y-1.
It’s B, because VKQ is equal to DKJ. VKQ is 153°, which makes DKJ 153°. But you’re trying to find DKM, which is 153°(the total degree) minus MKJ, the other half not including the one you’re trying to find. But we see a square there, a right angle, meaning that MKJ is equal to 90°
So we take the total of DKM (153°) and subtract it by the half that we know (which is MKJ, 90°) in order to find the half that we don’t know (DKM)
So it’s simply 153-90, which is 63°, so the answer should be B.
Hope this helped if you have other questions regarding this let me know! I know it seems a little confusing
