Answer 2

Answer:

Y = 72 degrees

Step-by-step explanation:

Let A be 2x and B be 3x

We know that A and B ae supplementary angles, So they add up to 180 degrees.

2x + 3x = 180

5x = 180

x = 180/5

x = 36 degrees

Angle A = 2x = 2*36 = 72 degrees

Angle B = 3x = 3*36 = 108 degrees

Angle A and Angle Y are Alternate Exterior Angles, So they are equal.

Angle A = Angle Y = 72 degrees

Angle Y = 72 degrees.
