Question

if a=3,b=4,c=5 then value of 2R​

Answer 1

Step-by-step explanation:

Because

Let (A/3)=(B/4)=(C/5)=k

=A=3k,B=4k,C=5k

=A:B:C=3k:4k:5k

A:B:C=3:4:5

Answer 2

$•\huge\bigstar \tt{\underline{{\red{A}{\pink{n}{\color{blue}{s}{\color{gold}{w}{\color{aqua}{e}{\color{lime}{r}}}}}}}}}\huge\bigstar•$

$\bold{Let( \frac{a}{3} ) = ( \frac{b}{4}) = ( \frac{c}{5}) = 5}$

$\bold{ = a = 3k \: b = 4k \: c = 5k}$

$\tt{a:b:c = 3k:4k:5k}$

$\bold \red{a:b:c = 3:4:5}$
