Question

four angles of a quadrilateral are in the ratio 3 : 4 : 5 : 6 . What is the measure of the smallest angle​

Answer 1

Answer:

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

Smallest angle=3x

According to question:-

3x+4x+5x+6x=360°(Sum of angles of a quadrilateral=360°)

18x=360°

$x = \frac{360\degree}{18}$

x=20°

Therefore,

Smallest angle=3x

=3×20°

=60°

Answer 2

Answer:

Smallest angle = 60°
