1. tiffers24

1.What is the length of RS? 2. What is the value of x? 3. What is the value of y? 4. What is the length of UW? 5. What is the length of UV?

2. amistre64

there seems to be alot of assumptions wed have to make for that picture to come up with any sort of solutions.

3. tiffers24

That's why im so confused

4. amistre64

assume all the triangles are similar to |dw:1361984775694:dw|

5. amistre64

2x = 11 3y = 15.9 and the side with the 12 on it can either be scaled or determine the similar proportion of the top segment

6. tiffers24

Okay thank you

7. amistre64

other than that, im as lost at it as you are :) good luck

8. tiffers24

Hahaha I'll try my best!

9. amistre64

if im still around, i can dbl chk what you get if you need me to

10. tiffers24

Ok thank you, i will post my answers once I'm done

11. amistre64

you say: 1. 24 2. 6 3. 5.3 4. 7.95 5. 12 id say x=11/2, y=16/3 for starters then the proportion$\frac{12}{11}=\frac{RS}{11+11/2}$ $\frac{12(11+11/2)}{11}=RS$ $12(1+1/2)=RS=18$

12. tiffers24

Okayy, i see i see

13. amistre64

but someting just doesnt sit right for me in that .... if 2x=11, then RS should equal 24

14. amistre64

lol, i did 11+11/2 and not 11+2(11/2) :)

15. amistre64

uv = 15.9 uw=11 x=11/2 = 5.5 y=5.3 rs=24 sounds good to me

16. tiffers24

Sorry i took so long, went on break but thank you so much :)

17. tiffers24

Those were all right :)
