Question

Which set of angle measures could be the measures of the interior angles of a triangle?

1. 60°, 42°, and 58°

2. 70°, 60°, and 50°

3. 110°, 38°, and 42°

4. 41°, 75°, and 70°

Answer 1

2. 70°, 60°, and 50°

Explanation:

All interior angles of a triangle MUST EQUAL 180°

1) 60 + 42 + 58 = 160

2) 70 + 60 + 50 = 180

3) 110 + 38 + 42 = 190

4) 41 + 75 + 70 = 186
