Question

Triangles ABC and XYZ are similar figures, because angles A, B, and C are congruent to angles X, Y, and Z, respectively.

If side AC equals 3 cm, BC equals 9 cm, and XZ equals 15 cm, what is the length of side YZ?

Answer 1

45cm

Explanation:

Since they are simliar, they are proportional.

SO, you can do AC/XZ = BC/YZ

You can also see that XZ is 5 times larger than AC

SO multiply BC by 5.
