Question

in a triangle ABC,the AB,BC are in the ratio 2:3 and the sides BC ,CA are in the ratio 4:5,what is the ratio of all sides​

Answer 1

Supposing a triangle ABC

AB/BC=2/3; BC/CA=4/5 [GIVEN]

Matching BC in both cases

AB/BC=2×4/3×4

BC/CA=4×3/5×3

AB/BC=8/12

BC/CA=12/15

A:B:C=8:12:15

HOPE IT HELPS!!!!

Answer 2

Given: in triangle abc

ab/ bc =2/3

bc/ ca=4/5,

now , take out ratios if the side

by the similarity

ab/bc=bc/ca

it's means

2/3=4/5

=4/5×3/2

=6/5.

Hence , ab/ bc=bc/ca=6/5

so the the ratio is 6:5
