Question

two angles of a quadrilateral are 68 degree and 76 degree if the other and two angles are in the ratio 5 is to 7 find the measure of each of them

Answer 1

let the side which is in ratio be 5x and 7x

as we know that the sum of angles of quadrilateral is 360

then,

68+76+5x+7x=360

12x=360-144

12x=216

x=216/12

x=18

then angles which area in ratio are

5(18) =90

and other will be 7(18)=126

then the angles are 126,90,68 and 76

Answer 2

I hope this will help !!
