Question

four angle of quadrilateral are in a ratio 1:3:5:9,find the larger angle​

Answer 1

Answer:

1:3:5:9

[Let x be the common factor]

So, angles are 1x, 3x, 5x, 9x

=> 1x + 3x + 5x + 9x = 360°

=> 18x = 360°

=> x = 360° / 18 = 20

Hence, the larger angle = 9x = 9x20 = 180°

Answer 2

Step-by-step explanation:

four angles = 1x+3x+5x+9x=360

18x=360

x=360÷18x=20

first angle =1x

1×20= 20

second angle=3x

3×20= 60

third angle =5x

5×20= 100

fourth angle = 9x

9×20=180

there fore the fourth angle is bigger among them
