If the angles of a triangle are in the ratio of 9 ∶ 11 ∶ 16, then the difference between the greatest angle and the smallest angle is:
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 35°.
Smallest angle = (9/36) × 180° = 45°
Greatest angle = (16/36) × 180° = 80°
Difference = 80° - 45° = 35°
