Question

(d) 100
2. The angles of a quadrilateral are in the ratio 3:4:5:6. The smallest of
these angles is
(a) 45°
(b) 60°
(c) 36°
(d) 48°​

Answer 1

Answer:

Let the angles be x then the angles are 3x,4x,5x,6x.

3x+4x+5x+6x=360° [Angle sum property of quadrilateral]

18x=360°

x=360°/18

x=20°

then, 3x=60

4x=80

5x=100

6x=120

Then, (b) is correct.
