Need help please!!!!!
Yanka [14]

Answer:

Side 1 = 8, side 2=6, side 3=3 1/3 or 10/3

Step-by-step explanation:

We can set up a proportion comparing the sides of the original triangle to the new triangle.

The original triangle has sides 12, 9, and 5. The new triangle has sides 8, e, and f (use whatever letters you like, it doesn't matter, but for me, e is the side with the middle length and f is the side with the shortest length.

We can write 3 ratios, with the length of the new triangle over the length of the old triangle.

8/12  e/9  f/5

To figure out e and f, put each ratio equal to 8/12.

<u>8  </u> =  <u>e</u>  Then multiply both sides of the equation by 9 and get <u>72 </u> = e, 6=e.

12     9                                                                                              12

<u>8  </u> =  <u>f </u> Then multiply both sides of the equation by 9 and get <u>40 </u> = f, <u>10</u>=f.

12     5                                                                                              12          3

10/3 can be rewritten as 3 1/3.
