Answer:
1, 2 and 4 option - Yes
3 option - No
Step-by-step explanation:
<u>Definition: </u>Vertical angles are the angles opposite each other when two lines cross.
By the definition options
- they are formed by intersecting lines,
- they are opposite to each other
are true.
Vertical Angles Theorem states that vertical angles are congruent. Thus, option
is true.
Option
- they are always supplementary
is false, because supplementary are angles that add up to 180°, but vertical angles can have different measures which do not add up to 180°.
If 20-2.3=17.7, then if you add 17.7 to 2.3. it equals 20 which is called the communicative property because whatever you add or subtract, the answer is the same
17.7+2.3=2.3+17.7
Answer:
just try to work and ask your teacher okay I have to find the key to it first

Is there any multiple choice answers?
Answer:
domain = {x|xER}
range = {y|y≥0,yER}
Step-by-step explanation:
|x| means the absolute value which in this case is the distance from 0. On a graph this function would look like a v and would mean it would have infinite x-values since it is opening upwards in both directions.
For the range the vertex of this function is (0,0), if the x-coordinate were 0 the y-coordinate would be 0 because the absolute distance from 0 is 0. for another x-coordinate say -2 the absolute distance from 0 is 2 meaning the y-value is 0 since y=|x|, making the coordinate (-2,2) meaning the range is every y value must be above 0 since there is no way for the y-value to be negative
