the angles of a quadrilateral are in the ratio 3 ratio 5 ratio 9 ratio 13 ratio find all the angle of the quadrilateral
Answers
Answer:
let angles be 3x ,5x,9x,13x
by angles sum property of triangle:-
3x+5x+9x+13x= 360
30x= 360
x=30/360=
x=12
3x= 3×12=36
5x=5×12=60
9x=9×12=108
13x=13×12=156
Answer:
36° , 60° , 108° , 156°
Step-by-step explanation:
Given---> Angles of a quadrilateral are in the ratio
3 : 5 : 9 : 13 .
To find ---> All the angles of quadrilateral .
Solution---> Let quadrilateral be ABCD and
ATQ, ∠ A : ∠B : ∠C : ∠D = 3 : 5 : 9 : 13
Let ∠A = 3x , ∠B = 5x , ∠C = 9x , ∠D = 13x
We know that sum of angles of quadrilateral are 360° , so applying this
∠ A + ∠ B + ∠C + ∠D = 360°
=> 3x + 5x + 9x + 13x = 360°
=> 30 x = 360°
=> x = 360° / 30
=> x = 12
So, ∠A = 3x = 3 ( 12 ) = 36°
∠B = 5x = 5 ( 12 ) = 60°
∠C = 9x = 9 ( 12 ) = 108°
∠D = 13x = 13 ( 12 ) = 156°
