A ramp represented by segment PQ in the figure below is used to load cargo on a truck. Maya wants to find the length of the ramp. What is the length of the ramp used?

|dw:1343697136414:dw| Triangle QST ~ Triangle QPR (AAA) $$\frac{9}{12} = \frac{15}{15+PQ}$$ Solve PQ.

3. LoveToDance22

@Callisto Is it 25?

4. Callisto

Nope, I don't think so.

5. Callisto

$\frac{9}{12} = \frac{15}{15+PQ}$ 9(15+PQ) = 12x15 Solve from here~

6. LoveToDance22

@Callisto I got PQ=5

7. Callisto

That's what I've got too!

8. Callisto

Oh... wait!

9. Callisto

It should be PS not PQ in the equation..

10. Callisto

$\frac{9}{12} =\frac{15}{PQ}$^ This is the right one to solve :( I'm sorry that I overlooked something !!!

11. LoveToDance22

@Callisto Lol, It's ok, is it PQ=20?

12. Callisto

Yes!

13. LoveToDance22

Thanks!
