Question

The angles of of a quadrilateral are 7x,10x,11x and 12x. Find the value of X and all the angles of the quadrilateral.

Answer 1

Answer:

x=80

Step-by-step explanation:

the sumall the angles of the quadrilateral = 360.

7x+10x+11x+12x=360

40x=360

x=80

Answer 2

Answer:

63,90,99,104

Step-by-step explanation:

7x,10x,11x,12x

7x+ 10x +11x +12x =360

40x=360

x=360/40=9

x=9

7x=7*9=63

10x=10*9=90

11x=11*9=99

12x=12*9=104
