The angle of a quadrilateral are in the ratio 11 is to 18 is to 21 is to
22 find all the angles of the quadrilateral
Answers
Step-by-step explanation:
let the angels be 11x, 18x, 21x, 22x
and we know sum of angles in a quadrilateral =360
so 11x+18x+21x+22x= 360
72x=360
x=360/72
x= 60/12
x= 5
so angles are 11*5=55
18*5= 90
21x =21*5= 105
22x= 22*5= 110
Answer:
- The value of each angle of given quadrilateral is 55° , 90° , 105° & 110° respectively .
Step-by-step explanation:
According to the Question
It is given that ,
Angle of Quadrilateral are in the ratio of 11:18:21:22 respectively .
we have to calculate the angles of the quadrilateral .
Let the ratio of quadrilateral be 11x 18x 21x 22x
As we know that sum of all angles in a quadrilateral is 360° .
So we will put the given ratio in, we get
↠ 11x + 18x + 21x + 22x = 360°
↠ 72x = 360°
↠x = 360/72
↠ x = 5°
Here, the value of x is 5° .
Now, calculating the value of each angle
↠ 11x = 11×5 = 55°
↠ 22x = 22×5 = 110°
↠ 21x = 21×5 = 105°
↠ 18x = 18×5 = 90°
- Hence, the value of each angle of given quadrilateral is 55° , 90° , 105° & 110° respectively .
