Answer:
46
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.
