Answer:
We know that since it's a square, the lenght size is the same on all sides. We can simply use pythagoras theorem:
a^2 + a^2 = 13.5^2
13.5^2 = 182,25
182,25 : 2 (because there are 2 'a') = 91,125
<u>The square root of 91,125 is 9,55 feet.</u>

Answer:
2y = x - 6
Step-by-step explanation:
First, we must find the slope of the current equation.
This is the number in front of the x.
Seeing as this is -2x, the slope of this line is -2
When finding the slope of a line perpendicular, you need to find the
So, in this case it is:
The negatives cancel out which leave
So the gradient is
Now, to find the equation of a line, you need to use:
y - y1 = m(x - x1)
Where ya and x1 are the values in the coordinates (2 , -2)
So y1 = -2, x1 = 2, and m is a half. Plug these values in:
y - - 2 =
We need to get rid of the half so we multiply the whole equation by 2:
2y - - 4 = (x - 2)
The minus and the negative turn into a positive:
2y + 4 = x - 2
And now simply move the +4 over to the other side, making it a negative:
2y = -2 - 4 + x
Simplify:
2y = x - 6
<h3>So the equation of the line is 2y = x - 6</h3>
