The sum of the measures of the angles of a triangle is 180 degrees.

y + 60 + 60 = 180

y + 120 = 180

y = 60

Answer: y = 60 deg, which is choice A.

Hey!

The sum of all 3 angles in a triangle is always 180°. Two of the angles are shown. Add the 2 angles and subtract that from 180.

60 + 60 = 120

The sum of the two angles is 120°. Subtract that from 180.

180 - 120 = 60

That means your answer is A. 60°.
