Question

The angles of quadrilateral are in ratio 3:4:5:6. Find the angles and name the quadrilateral

Answer 1

Step-by-step explanation:

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

Let these angles 3x°,4x°,5x°,6x°

By condition,

3x°+4x°+5x°+6x° = 180°

3x+4x+5x+6x = 180

18x = 180

x = 180/18

x = 10

The angles are

(3×10)° =30°

(4×10)° = 40°

(5×10)° = 50°

(6×10)° = 60°

This quadrilateral is a trapezium

Answer 2

Answer:

The angles are 60, 80, 100, 120 degrees

The quadrilateral is a Trapezium

Step-by-step explanation:

3:4:5:6

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

                      18x = 360

                          x = 360/18

                          x = 20

3x = 3*20

    = 60

4x = 4*20

    = 80

5x = 5*20

    = 100

6x = 6*20

    = 120
