Question

four angle of a quadrilateral are in the ratio of 4:5:6:9​

Answer 1

Step-by-step explanation:

let the angle is 4x,5x,6x,9x

then 4x+5x+6x+9x=360

24x=360

x=360/24=15

therefore the angles are 60 ,75,90,135

Answer 2

Answer:

The angles are

1)

360°×[4/(4+5+6+9)]=60°

2)

360°×[5/(4+5+6+9)]=75°

3)

360°×[6/(4+5+6+9)]=90°

4)

360°×[9/(4+5+6+9)]=135°
