The z-score will be given by:
z=(x-μ)/σ
given that:
x=94
μ=mean=84.5
σ=standard deviation=4.4
thus
z=(94-84.5)/4.4
z=2.1591
Factor out the GCF, which is 4.... 4(4a+3b)
All the triangles are similar, so you know the long side is twice the length of the short side.
x = 2·16 = 32
From the Pythagorean theorem,
z = √(8² + 16²) = √320 = 8√5
Then
y = 2z = 16√5
The appropriate choice is the 2nd choice,
x = 32, y = 16√5, z = 8√5
