Question

If the angle of triangle
3:4:5, then find value
of each ed angle
​

Answer 1

Answer:

Angle Sum Property of a triangle states that the sum of all interior angles of a triangle equals to 180°

1st angle = 3x

2nd angle = 4x

3rd angle = 5x

3x + 4x + 5x = 180°

7x + 5x = 180°

12x = 180°

x = 180°/12

x = 15°

Hence 1st angle = 3x

= 3 × 15°

= 45°

2nd angle = 4x

= 4 × 15°

= 60°

3rd angle = 5x

= 5 × 15°

= 75°
