ΔABC is similar to ΔDEF
Try to pair up all the similar sides.
AB = 15 cm
DE = ? cm
BC = 18 cm
EF = 6 cm
Now all you have to do is find out how the triangles are similar.
18/6 = 3
This means that triangle ABC is 3 times bigger than DEF.
15/3 = 5
So the answer is:
B. 5 cm

Step-by-step explanation:
In order for an integer to be even, one of the factors must be 2. Otherwise, it is odd.
If A is an odd number, it does not have a factor of 2.
If B is an odd number, it also does not have a factor of 2.
Therefore, AB also does not have a factor of 2, so it is always odd.
