The set of angles that can be used to construct a triangle is the one where the sum of the angles is equal to 180 degrees.
A: 66° + 47° + 64° = 177° (cannot form a triangle)
B: 40° + 73° + 65° = 178° (cannot form a triangle)
C: 78° + 56° + 46° = 180° (can form a triangle)
D: 110° + 30° + 27° = 167° (cannot form a triangle)
Therefore, the set of angles that can be used to construct a triangle is C: 78°, 56°, and 46°.
Which set of angles can be used to construct a triangle?
