@phi

Answer 1

any ideas?

Answer 2

60: x , I'm confused on the 48 part.

Answer 3

They will be using triangle SPT and triangle RPQ

Answer 4

make a ratio of side in SPT and the *corresponding side* of triangle RPQ

if we pick side SP in triangle SPT , any idea what the corresponding side is in the RPQ triangle?

Answer 5

60:x & 48: 36 is what I got.
@phi

Answer 6

side SP corresponds to side RP

Answer 7

Yes.

Answer 8

if you write the lengths:
60: (60+x)
is one of the ratios

Answer 9

another ratio is side TP : side QP

Answer 10

48 + 36 would be the other ratio ?

Answer 11

48+36 is the length of side QP, right?
you also need the side of TP

Answer 12

48: 48+36

Answer 13

Yes , for QP - correct!

Answer 14

yes, and we set those ratios equal
60: (60+x) =48: 48+36

Answer 15

Yay, thanks! :)
