Answer:
Yes
Step-by-step explanation:
To figure out if a triangle is a right triangle, you have to plug in the side lengths into the equation
+
= ![c^{2}](https://tex.z-dn.net/?f=c%5E%7B2%7D)
Your equation should look like ![5.1^{2} + 6.8^{2} = 8.5^{2}](https://tex.z-dn.net/?f=5.1%5E%7B2%7D%20%20%2B%206.8%5E%7B2%7D%20%20%3D%208.5%5E%7B2%7D)
Now you simplify. The equation should be: 26.01 + 46.24 = 72.25
Then add 26.01 and 46.24 to get 72.25 = 72.25
Since they are equal, the triangle is a right triangle.
Answer:
inverse
Step-by-step explanation:
4 is the additive inverse of -4
When you add opposites, they always have a sum of 0.
4 + -4 = 0
The additive inverse of a positive number is negative and vice versa.
------------------------------------
Given information
------------------------------------
Perimeter = 53m
Length is 2.3m longer than the width
------------------------------------
Formula
------------------------------------
Perimeter = 2( length + width)
------------------------------------
Define the length and Width
------------------------------------
Let the width be x
width = x
length = x + 2.3
------------------------------------
Form equation and solve x
------------------------------------
2( x + x + 2.3) = 53
2(2x + 2.3) = 53
4x + 4.6 = 53
4x = 53 - 4.6
4x = 48.4
x = 48.4 ÷ 4
x = 12.1
------------------------------------
Find Length and Width
------------------------------------
Width = x = 12.1m
Length = x + 2.3 = 12.1 + 2.3 = 14.4m
-------------------------------------------------------------
Answer: Length = 14.4m and Width = 12.1m
