Answer: A

Step-by-step explanation:

For this problem, we know that A is the correct answer. A is the same as the given expression because it is the same, but the order is switched. When you multiply both of them, you would get the same answer.

We can eliminate B because \frac{2}{5} should be positive, not negative.

We can eliminate C because the fraction should be \frac{2}{5}, not \frac{5}{2}.

We can eliminate D because (-1×-7) given you 7, not -7.

Therefore, A is the right answer.

A, B, and C are midpoints of ∆XYZ. What is the length of cy
iogann1982 [59]

Answer:

XY=36\ units

Step-by-step explanation:

<u><em>The correct question is</em></u>

A, B, and C are midpoints of ∆XYZ. What is the length of XY

we know that

The<u><em> Midpoint Theorem</em></u> states that the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side

step 1

Find the length of YZ

AB=\frac{1}{2}YZ

we have

AB=24\ units

substitute

24=\frac{1}{2}YZ

solve for YZ

YZ=48\ units

step 2

Find the length of XY

Applying Pythagoras Theorem in the right triangle XYZ

XZ^2=XY^2+YZ^2

substitute the given values

60^2=XY^2+48^2

solve for XY

3,600=XY^2+2,304

XY^2=3,600-2,304

XY^2=1,296

XY=36\ units

Applying the Midpoint Theorem

BC=\frac{1}{2}XY -----> BC=\frac{1}{2}(36)=18\ units

AC=\frac{1}{2}XZ -----> AC=\frac{1}{2}(60)=30\ units
