Question

Q10. The angles of a
quadrilateral ABCD taken in an
order are in the ratio 3:7:6:4,
then ABCD is a........​

Answer 1

given ABCD is a quadrilateral

angles 3:7:6:4

angle A =3

angle B=4

angle C=6

angle D =4

by sum of property of quadrilateralis=360

<A+<B+<C+<D=360

3+7+6+4=360

20=360

360÷20

= remainder is 18

18×3=54

18×7=126

18×6=108

18×4=72

54+126+108+72=360
