The angles of a triangle are in the ratio 2 : 3 : 7. What is the measure of the largest angle of the triangle?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 105°.
The sum of the angles in a triangle is 180°.
Ratio of three angles = 2 : 3 : 7
Largest angle = (7/12) × 180° = 105°
Therefore, the largest angle of the triangle is 105°.
