Question

☺☺☺guys plz solve this it is very important ☺☺☺
the measures of angle of quadrilateral ABCD are in the ratio 2 : 3 : 4 : 1 determine the type of the quadrilateral
​

Answer 1

Let the angles be 2x,3x,4x and x.

2x+3x+4x+x = 360°

or 10x = 360°

or x = 360°/10 = 36°

So, the angles are 72°, 108°, 144° and 36°.

Here, u can observe that sum of opposite angles is equal to 180°.

So, I think it's a cyclic quadrilateral.

2x + 3x + 4x + x = 360

10x = 360

x = 360 ÷ 10

× = 36

since the angles are 72 , 108 ,144 and 36
