Question

if 3A=4B= 5C find a:b:c

Answer 1

If it is a triangle then use use angle sum property
a+b+c=180.(a=b=c)
put the values

Answer 2

Answer:

20:15:12

Step-by-step explanation:

It is solved by a trick at first if u want to know a=then multiple the coefficient of b and c

And for b u have to multiple tne coefficient of a and c as respect c=multiple of coefficient of a and b

Therefore a:b:c=4*5:3*5:3*4

=20:15:12
