Question

What is the value of y?

Answer 1

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.

Answer 2

B

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
