Question

The angles of a quadrilateral are in the ratio 3:5:9:13.find all the angles of quadrilateral

Answer 1

Sum of all angles of quadrilateral= 360

So ratio

3+5+9+13= 30

360÷30=12

So each angle

(12*3), (12*5), (12*9),(12*13)

So all angles are

36° , 60°, 108°, 156°

Answer 2

Step-by-step explanation:

HERE IS YOUR ANSWER BUDDY

As you know angle sum of a quadrilateral = 360°

So, 3x + 5x + 9x + 13x = 360°

Or, 30x = 360°

Or, x = 12°

Hence, 3x = 36°, 5x = 60°, 9x = 108° and 13x = 156°
