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°
