Question

The angles of a quadrilateral are in the ratio of 3:4:5:6. Find their measures. (hint:- Sum of quadrilateral is 360o )​

Answer 1

Answer:

60o, 80o, 100o, 120o

Step-by-step explanation:

Let the 1st angle be 3x, 2nd angle be 4x, 3rd angle be 5x, 4th angle be 6x

Sum of angles in a Quadrilateral = 360o

Sum of ratio angles = 3x+4x+5x+6x = 18x

We can write as,

18x = 360o

x = 360o/18 = 20o

1st angle = 3x = 3×20o = 60o

2nd angle = 4x = 4×20o = 80o

3rd angle = 5x = 5×20o = 100o

4th angle = 6x = 6×20o = 120o
