Question

can u guys answer 6 7 8 9 questions

Answer 1

6. interior angle = supplement of 140
= 40 degrees
then, by exterior angle property,
X = 40 + 90
X = 130

7. interior angle = supplement of 120
= 60 degrees
then, by angle sum property of quadrilateral,
60 + x + 110 + 60 = 360
230 + x = 360
x = 130

8. x = 130
y = 60
z = 70
and supplement of w = 360 -110-120-50
=80
then, w = 100

and x + y + z + w = 130 + 60 + 70 + 100
=360 degrees

9. angle sum property of quadrilaterals,
x + y +110 + 60 = 360
x + y = 360 - 170
x + y = 190 degrees

Answer 2

6)Angle1= 40degrees
Because sum of adjacent angles of a triangle is 180.
140+40=180
Angle 2 is given as 90 degrees
Angle 3=50degrees
Since sum of angles of triangle is equal to 180degrees.
40+90+50=180degrees

X=130degrees
Sum of adjacent angles of a triangle is equal to 180degrees.
130+50=180degrees

7)Angle 4=60degrees. Reason-adjacent angles.

X=130degrees. Since sum of angles is 360degrees.
130+60+60+110=360degrees.

8)Angle 3=80degrees. Sum of angles=360degrees
X=180-50=130degrees. Adjacent angles sum=180degrees.

Y=60degrees since adjacent angles sum=180degrees
120+60=180degrees.

Z=70degrees since adjacent angles sum is 180.70+110=180degrees.

W=130degrees.
Sum of adjacent angles=180. 130+50=180degrees
130+60+70+130=360degrees.

Sum of angles is=360degrees.

9)110+60+x+y=360
X+y=360-170=190degrees
X+y=190degrees.

Hope it helps
