PART A)find x using the ratio of the sides 12 cm and 16 cm: x/20=12/16. Show your work

PART B) find x using the ratio of the sides 6 cm and 8 cm. Show your work

PART C) Explain why the answers to a and b should be the same

The triangles are
1st one x,12 cm, 6cm,
the 2nd one is 20 cm, 16 cm, 8 cm,

6 answers

a. x/20 = 12/16. So, here's what you do: 12 * 20 = 240. 240 / 16 = 15. As a way to doublecheck: 15 * 16 = 240 x = 15.
b. x/20 = 6/8. 6 * 20 = 120. 120 / 8 = 15. Here's another double check: 15 * 8 = 120 x = 15.
c. The answers to (a) and (b) should be the same because they are in ratio. Also, you are looking for x in both and it can't change what it's number is.

Thank you

Thx!

woah, thank you so much :D

Thanks for not helping and just making it more confusing.
