There is no such thing as subtraction. Just something to think about :)
There are numbers and there is an operation called addition. Every number has an additive inverse, an opposite value.
Example: The opposite of 4 is -4.
When we do addition between numbers like 5 and the inverse of 2: 5 + -2 this is usually what we're thinking of when we talk about subtraction. We could write it as 5 - 2.
But anyway, to answer your question,
Subtraction and division are derived from the principle operations of ADDITION and MULTIPLICATION.
Answer:
The answer is .................................................94
Answer:
Step-by-step explanation:
These bisectors intersect each-other at 90 degrees. And it means that they are perpendicular. Since they are perpendicular, we find that there 4 congruent triangles and XY is parallel to WZ and WX is parallel to YZ. Additionally, opposite angles are equal. These two latter findings are the characteristics of the parallelogram.
