Question

If ΔABC is similar to ΔDEF, and AB= 16, DF= 3, and AC= 12, what is the length of DE?

Answers

To find the length of DE, we can set up a proportion using the corresponding sides of the similar triangles:

AB/DE = AC/DF

Plugging in the given values, we get:

16/DE = 12/3

Cross multiply to solve for DE:

3*16 = 12*DE

48 = 12*DE

Divide by 12 on both sides:

DE = 48/12

DE = 4

Therefore, the length of DE is 4.
