Question

the angles of a quadrilateral are in the ratio 3:4:5:6.The smallest of these angles is-36or45or60or 50 degree​

Answer 1

Hola!!⤵️⤵️

Sum of all angles of a quadrilateral is 360°.

Let the angles be 3x, 4x, 5x and 6x

So,

3x + 4x+ 5x + 6x = 360

18x = 360

Solving we get:-

x = 20

So the smallest angle is 20 × 3 = 60°✔

Answer 2

Sum of quadrilateral is 360.

3x+4x+5x+6x=360

18x=360

x=360/18=20

The smallest no is 3x then put the value of x =20.

3x = 3*20= 60 ans
