Question

the four angles of a quadrilateral are in the ratio 4: 5: 6: 3, find the angles speretly​

Answer 1

Answer:

hi

Step-by-step explanation:

let ratio's be 4x,3x,6x,5x

sum of all the angles in a quadrilateral = 360

therefore, 4x+3x+5x+6x=360

18x=360

x=360/18

x=20 degrees

therefore 4x=80

3x=60

6x=120

5x=100

Answer 2

Given :

The four angles of a quadrilateral are in the ratio 4: 5: 6: 3,

To find :

The angles of Quadrilateral.

Solution :

We know that,

Sum of all angles of Quadrilateral is 360°

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

4x + 5x + 6x + 3x = 360°

➵ 18x = 360°

➵ x = 18/360

x = 20°

4x = 4 × 20 = 80°

5x = 5 × 20 = 100°

6x = 6 × 20 = 120°

3x = 3 × 20 = 60°
