Question

What is the scale factor from sjt to ect?

Answer 1

Answer: 3

Explanation:

The scale factor is the proportional ratio from one figure to another.

Notice the corresponding lengths are CE≅JS, TC≅TJ, and TE≅TS.

Comparing CE and JS, the length for CE is 4, and the length for JS is 12.

`4*3=12`

This means the scale factor is 3. To be sure, let's try the other side.

TC and TE have the same lengths. They are both 5 in length. TS is 15 in length.

`5*3=15`

This confirms that the scale factor is 3.
