Step-by-step explanation:
Powers of 10 is a very useful way of writing down large or small numbers.
Instead of having lots of zeros, you show how many powers of 10 will make that many zeros.
When you work with small numbers, you should use the negative powers of 10. Just remember for negative powers of 10, move the decimal point to the left. For example,
When comparing small numbers, write these numbers in scientific notation (only one non-xero digit must be before point) and then
- if the powers of 10 are the same in compared numbers are the same, just compare the numbers which are multiplied by these powers of 10. For example, because powers are the same (-6) and
- if the powers are different, then the smaller is power, the smaller is number (number with the smaller negative power has more places after decimal point). For example, because

Answer:
C. Vertical angles are supplementary if both are right angles.
Step-by-step explanation:
You want to know the conditions when vertical angles are supplementary.
<h3>Supplementary angles</h3>
Two angles are supplementary when they total 180°.
<h3>Vertical angles</h3>
Vertical angles are formed when two lines cross. They share a vertex, but not a side. Their sides are opposite rays.
Vertical angles are always congruent.
<h3>Supplementary vertical angles</h3>
If x is the measure of one of two supplementary vertical angles, then we must have ...
x + x = 180°
2x = 180° . . . . . collect terms
x = 90° . . . . . . . divide by 2
Vertical angles will be supplementary if and only if they are both right angles.
