What is the value of y?

Answer:
B
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, with 88 being the exterior angle and both y's the opposite interior angles, thus
y + y = 88
2y = 88 ( divide both sides by 2 )
y = 44 → B
Answer:
46
Step-by-step explanation:
consider the triangle to have 3 angles. y, y, and 88. (The reason for 88 is that 88 and the top corner of the triangle are equivalent.)
A triangle's sides must add to 180. Since both y angles are the same letter, we can assume that they are equal. 180-88= 92. 92 divided by 2, (since there are 2 'y's) = 46.
