How do I find the value of y?
Genrish500 [490]

Answer:

y = 27

Step-by-step explanation:

line segment BA and CD are congruent, turn them into an equation

3y - 59 = y - 5

subtract 1y from both sides, you get 2y - 59 = -5

then, add 59 to both sides and the equation is now 2y = 54

divide each side by 2 and you get the value of y (y = 27)
