A square garden has the endpoints listed below plot these points on a grid a. (- 7, 6) b .(- 2, -6) C. (10, -1 ) D. (5,11) use the pythagorean theory to find the side length, s, of any of the sides of the square a b C d from the question above
To find the side length, s, of any of the sides of the square, we can use the Pythagorean theorem.
The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
In this case, we can consider one side of the square as the hypotenuse, and the other two sides as the lengths of the legs of the right triangle.
Let's consider points A (-7, 6) and B (-2, -6). The length of the side AB can be found using the Pythagorean theorem.
Length AB = √((x2 - x1)^2 + (y2 - y1)^2)
= √((-2 - (-7))^2 + (-6 - 6)^2)
= √(5^2 + (-12)^2)
= √(25 + 144)
= √169
= 13
Therefore, the length of side AB is 13.
Similarly, you can calculate the length of side BC and side CD using the same method:
Length BC = √((x2 - x1)^2 + (y2 - y1)^2)
= √((10 - (-2))^2 + (-1 - (-6))^2)
= √(12^2 + 5^2)
= √(144 + 25)
= √169
= 13
Length CD = √((x2 - x1)^2 + (y2 - y1)^2)
= √((5 - 10)^2 + (11 - (-1))^2)
= √((-5)^2 + 12^2)
= √(25 + 144)
= √169
= 13
Therefore, the length of side BC and side CD is also 13.
Hence, the side length, s, of any of the sides of the square is 13.
Can you show the work for side AB a little simpler please
Certainly! Here's a simpler step-by-step calculation for side AB:
Length AB = √((x2 - x1)^2 + (y2 - y1)^2)
= √((-2 - (-7))^2 + (-6 - 6)^2)
= √((-2 + 7)^2 + (-6 - 6)^2)
= √(5^2 + (-12)^2)
= √(25 + 144)
= √169
= 13
Therefore, the length of side AB is 13.
Do I need all those parentheses in there
No, you don't need all those parentheses. Here's the simplified calculation for side AB without the unnecessary parentheses:
Length AB = √((-2 - -7)^2 + (-6 - 6)^2)
= √((5)^2 + (-12)^2)
= √(25 + 144)
= √169
= 13
Therefore, the length of side AB is 13.
Can you make that answer without all the parentheses
Certainly! Here's the answer without unnecessary parentheses:
Length AB = √((-2 - -7)^2 + (-6 - 6)^2)
= √((5)^2 + (-12)^2)
= √(25 + 144)
= √169
= 13
Therefore, the length of side AB is 13.
