Answer:
y= 11.4
Step-by-step explanation:
In an equilateral triangle, each angle is the same
180/3=60
So each angle equals 60
5y+3 =60
Subtract 3 from each side
5y +3-3 = 60-3
5y = 57
Divide by 5
5y/5 = 57/5
y = 11.4

The given pair of angles doesn't form any special pair of angles provided in the options , hence the Correct choice is none of these.
