Question

If the measures of the angles of a quadrilateral
ABCD are respectively in the ratio 1:2:3:4,
then
(1) AC = BC
(3) AD || BC
(2) AB II DC
(4) AD = BC
explain with steps. irrelevent answers will be reported​

Answer 1

Answer:

in quadrilateral sum of all sides=360°

let 1:2:3:4 =1x:2X:3x:4x

1x+2x+3x+4x=360

10x=360

x=360/10

x=36

1(36)=36

2(36)=72

3(36)=108

4(36)=144

then AB||DC
