Using the formula a² + b² = c² but reversing it to c² - b² = x² where x replaces the a for comprehension reasons

so this is the formula
c² - b² = x²

insert the numbers on the triangle in the picture
21² - 8² = 377

since 377 is squared and not the side length, we need to square root it to find x
√377 = 19.4~

Answer: x = 19.4

Which of the following sums would be under the radical symbol to find the distance between the points (7, -1) and (-8, -9)?
fomenos
The "distance formula" an extension of the Pythagorean Theorem is:

d^2=(x2-x1)^2+(y2-y1)^2  in this case:

d^2=(-8-7)^2+(-9--1)^2

d^2=(-15)^2+(-8)^2

d^2=15^2+8^2

d=√(15^2+8^2)

So the answer is 15^2+8^2

A point is reflected over the y-axis to graph a new point. Are the x-coordinates of these points opposite of each other? Hewp!
musickatia [10]
Well let's say you have a coordinate (2, -1)

Now if we reflect it upon the y-axis we'll end up at the coordinate (2,1)

We see that the x value is still the same.
