Question

which set of angle measures will not be the three interior angles of a triangle?A. 78°, 2°, 100°B. 52°, 52°, 52°C. 60°, 30°, 90°D. 13°, 37°, 130°

Answer 1

Explanation:

"B" could not be angles of a triangle. It forms a straight line. So the answer is "B"

Answer 2

The sum of an interior angle of a triangle is 180 degrees.

`\begin{gathered} A.78^(\circ)+2^(\circ)+100^(\circ)=180^(\circ) \\ B.52^(\circ)+52^(\circ)+52^(\circ)=156^(\circ) \\ C.60^(\circ)+30^(\circ)+90^(\circ)=180^(\circ) \\ D.13^(\circ)+37^(\circ)+130^(\circ)=180^(\circ) \\ \text{Hence, (B) is the right option.} \end{gathered}`
