Question

The angles four angles quadrilateral are ratio 3:5:7:9 find the angles

Answer 1

Answer:

45,74,105,135

Step-by-step explanation:

3x+5x+7x+9x=360

24x=360

x=15

3x=45

5x=75

7x=105

9x=135

Answer 2

Answer:

Angles are 45 : 75 : 105 : 135

Step-by-step explanation:

Sum of all angles ( interior angles ) in a quadrilateral is 360,

3x + 5x + 7x + 9x = 360

24x =  360

x = 360 / 24

x = 15

3x = 3 × 15

3x = 45

5x = 5 × 15

5x = 75

7x = 7 × 15

7x = 105

9x = 9 × 15

9x = 135

3 : 5 : 7 : 9 = 45 : 75 : 105 : 135
