Answer 2

Step-by-step explanation:

Hey friend, pls note whenever sum comes with ratio, take common multiple 'x'.

A =

$a = 5 \times x$

$b = 6 \times x$

$c = 4 \times x$

$d = 7 \times x$

So,

A= 5x

B=6x

C=4x

D=7x

Now, u have to solve remaining sum as per based on ur question.

One example,

if it's given a ABC, where 5:6:4 respectively,

take a common multiple as x and then u will get a, b and c as 5x, 6x and 4x respectively.

Then by applying Angle sum property of a triangle, solve the sum, then u will get the value of x as 15.

Now, substitute the value of x on A, B and C and u will get it's answer.

I hope this might have helped u out.
