Answer:

No this is not always true.

Step-by-step explanation:

If the statement "If the sun is shining, then it's not raining" is assumed to be true, is its reverse, "If it's not raining, then the sun must be shining,"

No this is not always true.

Let s suppose,

A = The sun is shining  

B = It's not raining.  

The the statement "If the sun is shining, then it's not raining" translates in mathematical terms to :  

If A then B or A => B  

However if A => B is true then B => A may or may not be true as have too little information.  

So we cannot always say that "If it's not raining, then the sun must be shining,"

No, because it might be cloudy instead.

This is just like the statement, "All squares are rectangles" yet "All rectangles are squares" is not true.

Jane took a piece of cardboard and cut out a triangle with measure 32°, 58°, and 90°, and side lengths 5 cm, 12 cm, and 13 cm. W
ioda
The answer is A. Right, Scalene.

This is because 90 degrees = a right angle

32 and 58 are smaller than 90, making it acute or scalene.
Isosceles means at least two sides are equal.
Equilateral means all sides are equal.

In this case, it is not isosceles or equilateral because the sides are not unequal.
It isn’t D. because that option doesn’t say “right”
