Question

2. The four anales of a quadricateral are in the ration
3:5 7:9. Find the angle
.
​

Answer 1

Answer:

Let these angles as 3x ,5x , 7x , 9x respectively  

ATQ  

3x + 5x + 7x + 9x = 360  

24x = 360  

2x  = 30  

x    = 15  

3x  =  45  

5x  =  75  

7x  =  105

9x  = 135

Answer 2

The correct question is :-

The four angles of a quadrilateral are in the ratio 3:5:7:9 .Find the angle ?

Solñ:- Let the angles be 3x° , 5x° , 7x° , 9x° .

Sum of all angles of a quadrilateral is 360°.

Thus ,

=> 3x° + 5x° + 7x° + 9x° = 360°

=>24x° = 360°

=> x = 15

Thus , angles are 36° , 75° , 105° , 135°.
