Question

Find the values of x,y and z in the diagram.Give reasons wherever necessary

Answer 1

sum of angles inside Quadrilateral =360°

90+90+112+y=360
y=68°


Now considering only above quadrilateral ,,
112+90+70+x= 360
x=88°

now take lower quadrilateral

y+90+z+110= 360
68+90+z+110=360
z=92°

Answer 2

90 +90+112+y=360

Y=68

Above quad.120+90+70+x=360

x=110'

Lower quad.y+90+z+110=360'

z=92'
