Square ABCD has a diagonal of 8 inches long. How many square inches is the area of the shape?
Nat2105 [25]
The diagonal of any square always occurs in a ratio of \sqrt2:1 relative to the square's sides. That means if s is the side length, then \sqrt2s=8 gives the length of the diagonal. It follows that s=\dfrac8{\sqrt2}.

Then the area of the square is

s^2=\left(\dfrac8{\sqrt2}\right)^2=\dfrac{64}2=32 square inches

In△XYZ , XY¯¯¯¯¯¯=7in , YZ¯¯¯¯¯=5in , and XZ¯¯¯¯¯=4in . This triangle is reflected across the x-axis to result in △X'Y'Z' . Whic
ki77a [65]

Answer:

B

Step-by-step explanation:

Reflection is a transformation that preserves lengths.

Triangle XYZ, with side lengths XY = 7 in, YZ = 5 in, XZ = 4 in, is reflected across the x-axis to result in △X'Y'Z'.

This means that corresponding sides have the same lengths:

  • XY = X'Y' = 7 in;
  • XZ = X'Z' = 4 in;
  • YZ = Y'Z' = 5 in.

Find the perimeters of both triangles:

P_{XYZ}=XY+XZ+YZ=7+4+5=16\ in\\ \\P_{X'Y'Z'}=X'Y'+X'Z'+Y'Z'=7+4+5=16\ in

Hence, only option B is true.
