Question

In a quadrilateral ABCD ,if triangle A,Triable B, triangle C and triangle D are in the ratio of 3:4:6:7 then the measures of the each angles of the quadrilateral are ....

Answer 1

Angle A=70

Angle B=80

Angle C=100

Angle D=110

Answer 2

the total sum of angles of quadrilateral is equal to 360°.

therefore,

sum of ratios given=3+4+6+7=20

so,first angle =3/20×360=54

second angle=4/20×360=72

third angle=6/20×360=108

forth angle=7/20×360=126

sum of all angles=126+108+72+54=360°
