Question

Which of the following are NOT the measures of the angles of a triangle?

73°, 42° and 65°

68°, 60° and 52°

41°, 68° and 71°

58°, 70° and 62°

Answer 1

58°, 70° and 62°

Explanation:

All angle measurements in a triangle must add up to 180°.

`73+42+65=180\\\\\boxed{180=180}\\\\\\68+60+52=180\\\\\boxed{180=180}\\\\\\41+68+71=180\\\\\boxed{180=180}\\\\\\58+70+62=180\\\\\boxed{190\\eq 180}`

The last set of measurements are not suitable for a triangle.

The correct answer should be the last set.

Hope this helps.
