Line XY is perpendicular to line CD at D. Which conclusion can be drawn?
guapka [62]
I have attached the choices given for this question

Answer:
measure angle XDC = 90 degrees

Explanation:
The term "perpendicular" implies that the angle formed between the two lines is 90 degrees.
These two lines do not have to be equal in length, they just intersect forming a 90-degree angle.

Comparing the explanation with the given choices, we would find that the only correct choice is:
measure angle XDC = 90 degrees

Hope this helps :)

5. Prove the conditional by proving the contrapositive:
Sunny_sXe [5.5K]

Answer + Step-by-step explanation:

<u>the conditional statement</u> :

For two positive integers n and m,

nm = 4 ⇒  (n = 1  or  m = 1)  or  (n=m= 2)

<u>the contrapositive</u>:

(n ≠ 1  and  m ≠ 1)  and  (n ≠ 2 or m ≠ 2) ⇒ nm ≠ 4

<u>Prove the conditional by proving the contrapositive</u> :

Suppose

m ≠ 1

and m ≠ 2

and n ≠ 1

⇒ nm ≠ 1 × n  and  nm ≠ 2 × n  and n ≠ 1

⇒ nm ≠ 4  (because 4 = 4 × 1 or 4 = 2 × 2)

<u>Conclusion</u>:

The contrapositive is true then conditional is true.
