angle.
25 points!

Answer 1

6 0°

Explanation:

sum the parts of the ratio, 2 + 4 = 6 parts

A linear pair of angles sum to 180°

Divide by 6 to find the value of one part of the ratio.

180° ÷ 6 = 30° ← value of 1 part of the ratio, thus

2 parts = 2 × 30° = 60° ← smallest angle

Answer 2

actually, this is worth 13 points. not 25. thanks!
