Question

Which set of three angles could represent the interior angles of a triangle?

499590, 720
0349, 459, 110
249, 510, 15°
45° 70°, 85°

Answer 1

45°, 70°, 85°

Explanation:

The sum of all 3 angles in any triangle needs to equal 180°.

45°, 70°, and 85° add up to a total of 180°.

The rest of the answers cannot be triangles since their angles are too large.
