The figure shows a patter of regular hexagon and equilateral triangles http://assets.openstudy.com/updates/attachments/4fc862a5e4b022f1e12ff3be-amoreno1094-1338532572177-star.png 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 .
