The lengths of the sides of a triangle are 15 cm, 20 cm, 30 cm. what are the lengths of the sides of a similar triangle that has a perimeter of 26 cm ?

6 cm, 8 cm, 12 cm

The perimeter of the reference triangle is  ...

... (15 +20 +30) cm = 65 cm

Then the similar triangle has a scale factor of ...

... (26 cm)/(65 cm) = 2/5

Multiplying the side lengths of the reference triangle by 2/5, we get ...

... {15 cm, 20 cm, 30 cm) × 2/5 = {6 cm, 8 cm, 12 cm}

These are the side lengths of the smaller similar triangle. (Check: their sum is 26 cm.)

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

first one is a: renaming a fraction. second one is c: de-c

my explanation is that these were the answers on edg : )
