Question

13. Angles of a triangle are in the ratio
2.3:4
(2 Points)
60 degree
90 degree
180 degree
80 degree​

Answer 1

Answer:

let the angles be 2x, 3x and 4x

sum of internal angles of a triangle is 180 °

therefore

2x + 3x + 4x = 180°

9x = 180°

x = 180/9

x = 20°

2x = 2× 20°

2x = 2× 20° = 40° --- 1st angle

2x = 3 × 20°

× 20° = 60° --- 2nd angle

4x = 4× 20°

× 20° = 80° --- 3rd angle

Answer 2

Answer:

Given:- Ratio = 2:3:4

Sum of Ratio terms = (2+3+4) = 9

Total sum of all the angles in a triangle = 180°

Angle 1 = 2/9×180

= 40°

Angle 2 = 3/9×180

= 60°

Angle 3 = 4/9×180

= 80°

Ans:- Angle 1 = 40°

Angle 2 = 60°

Angle 3 = 80°
