Question

9. Find the length of TR if TL = 24 and TR:RV:VL is 3:4:5

Answer 1

length TR = 6

Explanation:

Length TL = 24

scale ratio = 3:4:5

T-------R--------V----------L

find: TR

24 / (3+4+5) = 2

length TR at 3 x 2 = 6

length RV at 4 x 2 = 8

length VL at 5 x 2 = 10

a total of 6 + 8 + 10 = 24

therefore,

length TR = 6
