Answer:
The length of third side is 4 units
Step-by-step explanation:
In a right angle triangle
AB = 2√3, BC = 2 and m∠B = 90°
Now, By Pythagoras Theorem
(AC)² = (AB)² + (BC)²
(AC)² = (2√3)² + (2)²
(AC)² = 12 + 4
(AC)² = 16
√(AC)² = √16
AC = 4
Thus, The length of third side is 4 units

Let's say that the coordinates of the squirrel are: (x, y)
Since the coordinates of the acorn is halfway, between the tree and the squirrel, that means the acorn is the midpoint.
To work out the midpoint you do:
(sum of x-coordinates) divided by 2, (sum of y coordinates) divided by 2.
We can use this to form an equation .
So the sum of the x coordinates of the tree and the squirrel = -1 :
x-coordinates of the squirrel:
<em>(now solve for x)</em>


y-coordinates:
<em>(now solve for y)</em>


So the coordinates of the squirrel are: (1, 2)

The student made error in step 2 because negative multiplied by positive is negative. Also negative multiplied by negative is positive
9/x = 4/12
cross multiply
4*x = 9*12
x = 9*12/4
x = 9*3
x = 27
