Question

Find and explain thiisisis

Answer 1

x will be 360°-(90+70+112)=360-272=88° (Angle sum property of quadrilateral)

z will be 180-88=92° (linear pair)

<1+70°=180 (linear pair)
<1=110°

y will be 360-(110°+92°+90°)
<y=360-292=68° (Angle sum property of quadrilateral)

Answer 2

in ABCF, according to the angle sum property of a quadrilateral,the sum of all angles is 360°
therefore,112°+90°+70°+x=360°
=272°+x=360°
=x=360°-272°
=x=88°
now, angle CFY+70°=180°. (linear pair)
=angel CFY=110°
and z =180°-88°. (linear pair)
=z=92°
as in CFED,y+z+90°+110°=360°
y+92°+90°+110°=360°
y=360°-292°
y=68°
