what is the value of y?

Answer:
54 degrees
but i think its 63 degrees now
Step-by-step explanation:
because i think this is an equilateral triangle
edit
wait i think its actually 63 because a triangle is 180 degrees and when you add..
54 + 63 + 63 = 180
Answer:
D. 63°
Step-by-step explanation:
sum of angles in a triangle = 180°
therefore
y + y + 54 = 180
2y + 54 = 180
2y = 126
y = 63°
