Question

1. The angles of a triangle are in the ratio of 1 : 3 : 5. find the main feature of each angle.

sorry friends the first question that I was incorrect so this is the correct one​

Answer 1

Step-by-step explanation:

Let angles be x.

1st angle = 1x

2nd angle = 3x

3rd angle = 5x

According to question,

1x + 3x + 5x = 180°

=> 9x = 180°

=> x = 180/9

=> x = 20°

1st angle = 1 × 20 => 20°

2nd angle = 3 × 20 => 60°

3rd angle = 5 × 20 => 100°
