Answer:
A
Step-by-step explanation:
In order to find y, or both of the y's since they are the same, it would be helpful to find the supplement of 130. 180 - 130 = 50. That means that the vertex angle is 50. So according to the Triangle Angle Sum Theorem, all the angles of a triangle have to add up to equal 180, so 180 - 50 = 130. But we have to divide that 130 in half to split it between the 2 y values which are equal. 130 divided in half is 65. So y = 65. Choice A is the one you want.
