Y=3

Step-by-step explanation:

23. y =3 because if the shorter base is 8 you add 8+4 because the longer base is x+4 and x=8 then when you add 8+4 you get 12 and once you get 12 you find out the 12+6=26 so you have to divide the 6 by two because you have 2 legs and that gives you 3 and 3+3=6 so you have your answer
