Answer:
x = 30°
Step-by-step explanation:
We know that the sum of all of the interior angles of a triangle is 180°, therefore, we can write the following equation:
x + 2x + 3x = 180
6x = 180
x = 30°
Purple = 1/5 of the colors
5 colors per tray, 20 trays = 5 * 20 = 100 colors
1/5 * 100 = 100/5 = 20
20 colors are purple
20/100 = 1/5
1/5
