Answer 1

Answer:

Step-by-step explanation:

The measure of each of these angles is 45,75,105 and 135.   The angles of a quadrilateral are in the ratio 3 : 5 : 7 : 9.

Answer 2

Step-by-step explanation:

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

.3x+5x+7x+9x=360

24x=360

2x=30x

=30/2x

=15

The angles of quadrilaterals are

3x = 3*15=45

5x =5*15=75

7x =7*15=105

9x =9*15=135

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