Question

The ratio offour angles of a quadrilateral is 3: 7: 5: 9: .find the angle.​

Answer 1

Answer:

sum of s quadrilateral is =360°

=> let the angles be 3 x,7x,5xand9x

=>3x+7x+5x+9x=360°

=>24x=360°

=>x=360°/24=15

therefore x=15 then

3x=3*15=45

5x=5*15=75

7x=7*15=105

9x=9*15=135

45+75+105+135=360°

tell is it right or wrong

Answer 2
