Question

The angle of the triangle ar in ratio 2: 3: 4 . The largest angle is​

Answer 1

Ratios of angles of a triangle = 2:3:4

Let the common multiple be x

1st angle = 2x

2nd angle = 3x

3rd angle = 4x

According to the angle sum property of a triangle

1st angle + 2nd angle + 3rd angle = 180⁰

2x + 3x + 4x = 180⁰

=> 9x = 180⁰

=> x = 180/9

=> x = 20⁰

1st angle = 2x = 2×20 = 40⁰

2nd angle = 3x = 3×20 = 60⁰

3rd angle = 4x = 4×20 = 80⁰

Therefore the largest angle is the 3rd angle.
