You can make the equilateral triangle into a right triangle by cutting it in half. So, your sides would be 4.5, 9, and x.
Using Pythagorean Theorem, you know that a^2 + b^2 = c^2.
The 'a' would be equal to 9, and 9^2 is equal to 81.
B is equal to 4.5, and 4.5^2 is 20.25.
So, you have the following:
81 + 20.25 = c^2
And that makes 'c' equal to 101.25.
The square root of 101.25 is approximately equal to 10.06.
So now you know the height, 10.06.
your answer is B (0,4), in the first equation you have to greater than -2, 4 is, 0+4=4.
so B is your answer

Step-by-step explanation:
Answer:
The answer is partial counterbalancing. a technique for controlling progressive error by using some subset of the available sequences of treatment conditions.
And complete counterbalancing. a process of arranging a series of experimental conditions or treatments in such a way that every possible sequence of conditions is given at least once during the study.

you can use that to figure it out
