Question

angles of a quadrilateral are in the ratio 3:4:4:7. Find all the angles of the quadrilateral.​

Answer 1

Step-by-step explanation:

let the angles be :-3x, 4x, 4x, 7x

we know that sum of all angles of a quadrilateral is 360

So,

3x+4x+4x+7x=360

18x=360

x=360/18

x=20°

Answer 2

Step-by-step explanation:

Let the angles of quadrilateral be

3x , 4x , 4x , 7x .

Sum of all Angles of quadrilateral is 360°

NOW

3x + 4x + 4x + 7x = 360°

18 x = 360°

x = 360°/18

x = 20°

Hence the value of x is 20°

$3x = 3 * 20 = 60° \\ \\ </p><p></p><p>4x = 4* 20 = 80° \\ \\ </p><p></p><p>4x = 4* 20 = 80° \\ \\ </p><p></p><p>7x = 7* 20 = 140°</p><p></p><p> </p><p></p><p>$
