Question

The ratio of the interior angles of a triangle is 2 : 3 : 4. What are the angle measures? Write the angle measures from least to greatest.

Answer 1

9514 1404 393

Answer:

40°, 60°, 80°

Explanation:

The total of ratio units is 2+3+4 = 9.

The total of angles in a triangle is 180°, so each ratio unit stands for 180°/9 = 20°.

The angle measures are ...

20° × 2 = 40°

20° × 3 = 60°

20° × 4 = 80°
