You can use the pythagoras theorem.
20^2=5^2+x^2
x^2=400-25
x^2=375
x = 19.36
20-19.36=0.64 feet
The answer is 0.64 feet :)
Answer:

Step-by-step explanation:
Answer:
Not a right triangle
Step-by-step explanation:
We can figure out if it is a right triangle or not by using the pythagorean theorem.
a^2 + b^2 = c^2
In this case a and b are 16 and 18
In order for it to be a right triangle, c has to equal 34, in this problem.
16^2 + 18^2 = c^2
= 580^2
= = 24.0832
Since 24.0832 does not equal 34, this is not a right triangle
Answer:
(3, 6)
Step-by-step explanation:
You add the x points together and divide by two, then you add the y points together and divide by 2.
Answer:
i think it's 13
Step-by-step explanation:
perimeter is L+ L+W+W
27+27=54
80-54=26
26/2=13
