Question

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

The sum of the measures of the angles about a vertex is 2y + the sum of two interior angles of the triangle. y = (360°- 240°) ÷ 2.

The sum of an interior angle of the hexagon and an interior angle of an equilateral triangle is 360°. y = 360° – 60°.

The sum of an interior angle of the hexagon and an interior angle of each of two equilateral triangles is 180°. y = 180° – 120°.

The sum of 2y and an interior angle of each of two equilateral triangles is 360°. y = (360°- 120°) ÷ 2 .

Answer 1

is there a drawing that goes with this?

Answer 2

yes sorry i forgot!

Answer 3

If you draw out a hexagon and an equilateral triangle, and calculate the interior angles, you'll see that the hexagon has interior angles of 120 degrees while the triangle has interior angles of 60 degrees.

Answer 4

So "The sum of an interior angle of the hexagon and an interior angle of each of two equilateral triangles is 180°."
