Question

if angle of a quadrilateral are ratio 3 5 7 15 then find all angles

Answer 1

Answer:

1st angle = 3 × 12 = 36°

2nd angle = 5 × 15 = 75°

3rd angle = 7 × 12 = 84°

4th angle = 15 × 12 = 180°

Step-by-step explanation:

Let the angles of quadrilateral = 3x, 5x, 7x, 15x

So,

3x + 5x + 7x + 15x = 360 °

30x = 360°

x = 360/30

x = 12

Therefore angles are :

1st angle = 3 × 12 = 36°

2nd angle = 5 × 15 = 75°

3rd angle = 7 × 12 = 84°

4th angle = 15 × 12 = 180°
