Answer:
1.5 and -1.5
Step-by-step explanation:
The coordinate of A is 0. It is given that AR = 3. AR represents the distance from point A to point R. Remember that distance is always positive. So, from here we have two possibilities.
- Point R is on Right side of A i.e. at coordinate 3
- Point R is on Left side of A i.e. at coordinate -3
In both of these cases AR which is the distance from A to R will be 3.
So, if R is on Right side of A, the midpoint of AR would be:

Or if R is on Left side of A, the midpoint of AR would be:

Thus, the possible coordinates of the midpoint of AR are 1.5 and -1.5
The answer is 40.74kg because you divide my 100, multiply by three ad subtract from 42!
14x+2y=6 (1)
-7x-2y= -13 (2)
Multiply (2) by 2, we have:
-14x-4y= -26 (3)
Take (1)+(3), we can solve and get x= -1, y= 10~
Answer:
2nd option
Step-by-step explanation:
Using the sine ratio in the right triangle
sin32° =
=
=
( multiply both sides by 6 )
6sin32° = BC
