Question

solve this plese chapt 12 quadrilateral

Answer 1

1...by angle sum property of quadrilateral

a+b+c+d=360
100+98+92+d=360
290+d=360
d=70

therefor angle 4 is 70 degree.

2....

let all angles be x then
by angle sum property

x+2x+3x+4x=360
10x=360
x=36

angle 1=x===36
angle 2=2x==72
angle 3=3x==108
angle 4=4x==144

Answer 2

hey mate!✌✌


2nd sum: angle A=1x
angle B=2x
angle C=3x
angle D=4x



A + B + C + D =180 DEGREE
1X +2X+3X+4X=180 DEGREE
10X=180 DEGREE
X=180/10
X =18

ANGLE A = 1X = 1×18 =18
ANGLE B= 2X=2×18 =36
angle c =3X =3×18=54
ANGLE D=4X =4×18=72


CHECK THIS ANSWER VERY WELL
& MARK ME AS A BRAINLIST ✌✌
