Question

The angle of quadrilateral are in the ratio 3 :4: 5: 6: the smallest of this angles is

Answer 1

Answer:

the angles are in the ratio 3:4:5:6

so let all the angles be 3x,4x,5x,6x

we know that the sum of all the angles in a quadrilateral is 360° so,

3x + 4x +5x + 6x = 360°

= 18x = 360°

= x = 360/18

= x = 20°

now the smallest angle was in the ratio 3x so,

3x = 3(20°)

= 60°

so the smallest angle is 60°

Answer 2

Answer:

Here is ur answer mate

Step-by-step explanation:

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

$= > 3x + 4x + 5x + 6x = 360 \: \\ degree \\ = > 18x = 360 \: degree \\ = > x = 360 \div 18 = 20 \\ = > x = 20 \: degree \\ = > 3 \times 20 = 60 \: degree \\ = > 4 \times 20 = 80 \: degree \\ = > 5 \times 20 = 100 \: degree \\ = > 6 \times 20 = 120 \: degree$

So the smallest angle is 60 degree
