Question

The four angles of a quadrilateral are in the ratio
3:5:7:9, the least angle will be -​

Answer 1

Answer:

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

24x equals to 360 degree

Therefore x = 360/24

x = 15

There 3x = 3*15 = 45

5x = 5*15 = 75

7x = 7*15 = 105

9x = 9*15 = 135

Therefore, the least angle will be of 45 degree.
