Question

The angles of a quadrilateral are in the ratio 7:8:9:12. Find all the angles of the quadrilateral.​

Answer 1

Step-by-step explanation:

Let the required angles of Quadrilateral be 7x, 8x, 9x and 12x.

We know,

7x + 8x+ 9x + 12x = 360

36x = 360

x = 10

7x = 7× 10 = 70

8x = 8×10=80

9x = 9×10 =90

12x = 12× 10 = 120

Answer 2

le that the angle b 7 x ,8 x ,9 x, 12 x

sum of all all angles of a quadrilateral is equal to 360 degree

7x+8x+9x+12x=360

36x=360

×=10

7x=7×10=70

8x=8×10=80

9x=9×10=90

12x=12×10=120

therefore , 70+80+90+120= 360°
