Question

In a quadrilateral ABCD ,AB|DC .If angle A:angle D 2:3angle B:C 7:8 find the measure of each angle

Answer 1

hiii. .....friend

the answer is here,

In quadrilateral ABCD , AB||DC.

So, AngleA+AngleD =180. ( Interior same side).

=> AngleB+AngleC =180.

Ratio of AngleA:D =2:3.

AngleA =2/5×180.

=> 2×36

=> 72.

AngleB =7/15×180.

=> 7× 12

=> 84.

AngleC = 8/15×180.

=> 12×8.

=> 96.

AngleD =3/5×180.

=> 3×36

=> 108.
