Question

The angles of a trapezoid in ratio 3:7:6:4

Answer 1

Step-by-step explanation:

A trapezoid is a qiadralatral hence the sum of all int angles is 360⁰

let the angles be 3x,7x,6x,4x,

So,

3x+7x+6x+4x=360

=>20x=360

=>x=360/20

=>x=18

Therefore the angles are

3x=3(18)=54⁰

7x=7(18)=126⁰

6x=6(18)=108⁰

4x=4(18)=72⁰

To chk the above results....add them and chk if you get 360.

Answer 2

Answer:

Step-by-step explanation:

sum of the angles of trapezoid is 360 degree

ie; 3x+7x+6x+4x=360

    20x=360

        x=18 degree

ie; 3x=3*18 = 54 degree

    7x=7*18 = 126 degree

    6x=6*18 = 108 degree

    4x=4*18 = 72 degree

therefore; the angles of the trapezoid is 54,126,108,72 degrees resspectevly
