Answer :
Answer:
60∘
Step-by-step explanation:
Let the angles be
3x, 4x 5x and 6x.
∵Sum of interior angles of a quadrilateral =360∘
⇒3x+4x+5x+6x=360∘
⇒18x=360∘
⇒x=360∘18
⇒x=20∘
∴ The angles are -
3x=3×20=60∘
4x=4×20=80∘
5x=5×20=100∘
6x=6×20=120∘
∴ The smallest angle is 60∘.

Answer:
60°
Step-by-step explanation:
You can let the angles as 3x , 4x, 5x and 6x
And as we know sum of angles of quadrilateral is 360°
According to question,
3x + 4x + 5x + 6x = 360°
18x = 360°
x= 360/ 18
x=20
now multiply
3 × 20 = 60
4 × 20 = 80
5 × 20 = 100
6 × 20 = 120
so smallest angle is 60°
