Question

The angles of a quadrilateral are in ratio 1∶1∶3∶7. Find each angle of the quadrilateral.

Answer 1

Answer:

Let the common ratio of angles be x

so first angle is x

second angle is x

third angle is 3x

fourth angle is 7x

x+x+3x+7x= 360

12x =360

x= 360÷12

x=30

first angle is 30

second angle is 30

third angle is 90

fourth angle is 210

Step-by-step explanation:

Answer 2

Answer:

The angles are 30,30,90,210 Degree.

Step-by-step explanation:

let the angle of Quadrilateral be x, x, 3x, 7x

As we know the sum of all interior angles of a Quadrilateral is 360 degree.

A. Q

=> x+x+3x+7x = 360

=> 12x = 360

=> x = 360/12

Therefore, x = 30

Now,

The angles of Quadrilateral = x = 30

3x = 3 × 30 = 90 , 7x = 7 × 30 = 210
