angles.​

Answer 1

Answer:

Step-by-step explanation:

The measure of each of these angles is 45,75,105 and 135.

Step-by-step explanation:

Given : The angles of a quadrilateral are in the ratio 3 : 5 : 7 : 9.

To find : The measure of each of these angles ?

Solution :

We know that,

Sum of angle of quadrilateral is 360°.

The angles of a quadrilateral are in the ratio 3 : 5 : 7 : 9.

Let x be the common ratio.

 

 

   

   

The angle of quadrilaterals are

The measure of each of these angles is 45,75,105 and 135.

Answer 2

Answer:

sum of all angles=360°

3x+5x+7x+9x=360°

x=360/24

x=15

angles are 45°, 75, 105, 135
