Question

Which of the following describes the correct method to find the measure of angle y?

The exterior angle of the hexagon is the angle of the equilateral triangle. y = 60°.

The exterior angle of the hexagon is the interior angle of the equilateral triangle. y = 180° – 60°.

The exterior angle of the hexagon is the exterior angle of the equilateral triangle. y = 180° – 120°.

The interior angle of the equilateral triangle and y are supplementary angles. y = 90° - 60°.

Answer 1

I'm pretty sure it's B but I want to verify
