If 2/3 = x/y, then which of the following must be true?
(2 + x)/3 = (x + 2)/y
3/2 = x/y
(2 + 3)/3 = (x + y)/y
(2 + 1)/3 = (x + 1)/y

C is correct

Step-by-step explanation:

Given:

We need to choose correct option which is equivalent to given equation.

Add both sides 1

Taking LCD and simplify it

Hence,  

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
