Question

plz answer it.friends

Answer 1

The 11th answer is 40 ( as in cyclic qu . the sum of opposite angles are is 180)

The angle CEF = 90
And DEF = 55
EF PARALLEL TO CD
So, angle EDC = 55 ( alternative angle)
Angle EDC + angle Y = 180 ( linear pairs )
So angle Y = 135
Angle y = angle z
So, z = 135
