Question

the angle of triangle are in ratio 1:3:5 find the greatest angle​

Answer 1

let the angles be x , 3x nd 5x

x° + 3x° + 5x° = 180° { sum of angles of triangle }

=> 9x° = 180°

=> x° = 20°

hence the angles are :-

=> x° = 20°

=> 3x° = 3 × 20°

= 60°

=> 5x° = 5 × 20°

= 100°

Therefore the greatest angle of the ∆ is 100°
