Given:-the ratio of the measures of the interior angles of a quadrilateral is 3:5:7:9
We know the sum of all the interior angle of a quadilateral = 360
let the four angles be 3x, 5x, 7x, 9x (since the ratio of angles are given)
By angle sum property of a quardilateral we get
3x + 5x + 7x + 9x = 360
now i hope you can calculate the value of x from there and therby you can get the value of all the four angles ,
hope this will help you |
