Question

The angles of a quadrilateral are in the ratio 9 : 8 : 4 : 15.  Find the measure of each angle​

Answer 1

Answer:

Step-by-step explanation:

Let the common ratio of angles be x

so angles are 9x, 8x, 4x, 15x

9x+8x+4x+15x=360  {sum of all angles of a quadrilateral is 360}

36x=360

x=360/36

x=10

so all the angles will be

9x=9*10=90

8x=8*10=80

4x=4*10=40

15x=15*10=150
