Question

4. If angles of a quadrilateral are in the ratio 3: 5:7:9, then find the measure of all the angles of
quadrilateral
is​

Answer 1

Answer:

Let the common ratio be x. Then the four angles of the quadrilateral are 3x, 5x, 7x, 9x. so the four angles of the quadrilateral are 45°, 75°, 105° and 135°.

Answer 2

Step-by-step explanation:

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

15x +9x =360

24x =360

x = 15

3x =45

5x =75

7x =105

9x =135
