similar triangles

4. aminah.love18

ya i think so lol this is all new to me

5. bahrom7893

TS = 49..

6. bahrom7893

ill let angela finish lol

7. aminah.love18

lol

8. bahrom7893

angela?.. okay ill take over

10. bahrom7893

the ratios in similar triangles are the same.

11. bahrom7893

Therefore: TU/ TV = TR/TS

12. bahrom7893

TU/21 = TR/TS TU/21 = TR/49 (TS = TV+VS = 21+28=49)

13. bahrom7893

TR = TU + UR = TU+8

14. bahrom7893

TU/21 = (TU+8)/49 TU = 21(TU+8)/49 TU = 3(TU+8)/7

15. bahrom7893

7TU = 3TU + 24 4TU = 24 TU = 6

let TU=x TS=TV+VS=21+28=49 similar triangle so TS/(x+8)=TV/x 49/(x+8)=21/x 49x=21x+168 28x=168 x=168/28=6 x=TU=6
