Which list of numbers is in order from greatest to least?

Based on the triangle diagrams, which statement is correct?

• k = 310° since 60 + 70 = 130 and 180 + 130 = 310

• k = 170° since 180 - 70 = 110 and 110 + 60 = 170

• k = 130° since 180 - 60 - 70 = 50 and 180 - 50 = 130

• k = 50° since 60 + 70 = 130 and 180 - 130 = 50
