Question

find the measure 4 angles of a quadrilateral if they are in the ratio of 3:5:7:9

Answer 1

Measure of all the angles of a quadrilateral = 360 °
3x + 5x +7x +9x = 360°
24x = 360
X = 360/24 =15
3x =45
5x =75
7x =105
9x =135

Answer 2

So we conclude that 3:5:7:9

SO we can write 3x,5x,7x and 9x

SO the sum a quadrilateral is 360°

3x+5x+7x+9x=360°

24x=360°

x=15

3×15=45

5×15=75

7×15=105

9×15=135

Hope this will help u.....
