Answer : The XZ is congruent to AC.
Step-by-step explanation :
First we have to prove ΔOBC and ΔOYX are congruent triangles.
Proof:
Side OC = Side OX (radius of same circle)
Side OB = Side OY (equal to 22)
∠B = ∠Y (equal to 90°)
ΔOBC ≅ ΔOYX (By SAS congruency)
So, Side BC = Side YX (By CPCT)
Similarly, Side AB = Side ZX
Or we can say that,
Chord XZ = Chord AC
Hence, the XZ is congruent to AC.

Answer:
S = 85cm^2
Step-by-step explanation:
The surface area of a square pyramid is given by the following formula:
where it has taken into account the sum of the area of a square and four triangles:
h: slant height = 6cm
b: base = 5cm
By replacing in the formula you obtain:
hence, the surface area is 85cm^2
