Question

In
a quadrilateral, the angles are in a ratio of 3 :4 :5 :6
Find the smallest
angle.
​

Answer 1

step step by step explanation

Answer 2

Let the first angle be 3x

Let the second angle be 4x

Let the third angle be 5x

Let the fourth angle be 6x

Sum of all angles in quadrilateral = 360°

3x+4x+5x+6x=360°

18x=360°

X=360°/18

X=20°

first angle= 3×20° = 60°

second angle= 4×20° = 80°

third angle= 5×20° = 100°

fourth angle= 6×20° = 120°

So, the smallest angle is 60°.
