Question

p.4 Passage: The angles of a quadrilateral are in ratio 3:5:7:9

1. If measure of angles be 3x, 5x, 7x, 9x, then the value of x is
20°
15°
25°
10°​

Answer 1

Step-by-step explanation:

Answer

Correct option is

A

36,60,108,156

Let the four angles of the quadrilateral be 3x, 5x, 9x and 13x

3x+5x+9x+13x=360

∘

[sum of all angles of the quadrilateral is 360

∘

]

30x=360

∘

x=12

∘

Hence, the angles of the quadrilateral are 3×12

∘

=36

∘

,5×12

∘

=60

∘

,9×12

∘

=108

∘

and13×12

∘

=156

∘
