Answer:
∠ Y = ∠ V
∠ Z = ∠ W

Step-by-step explanation:
It is given that Δ XYZ is similar to Δ XVW.
Since corresponding angles of similar triangles are equal,
∠ X = ∠ X
∠ Y = ∠ V
∠ Z = ∠ W
Also, since corresponding sides of similar triangles are in proportionate,

Let the side length of the square be x, then A = x^2
but diagonal (z) = sqrt(2x^2)
z^2 = 2x^2
x^2 = 1/2 z^2
Thus, A = 1/2 z^2
dA/dz = 1/2 (2z) = z
The rate of change is z.
When z = 4, the rate is 4.
Answer:
C
Step-by-step explanation:
Use the pythagorean theorem
a² + b² = c²
3² + 4² = c²
9 + 16 = c²
25 = c²
5 = c
