Please help :) I Will mark brainliest :) you are suppose to submit with a root

i recommend using something like reverse pythagreom theorm

Step-by-step explanation:

like so a^2 would usually be the long line but in this case its x so then try c^2 - b^2

in doing so you will get 225 - 81 sub that and you will get 144 the square root of that is 12 so then x would be 12

x = 6

Step-by-step explanation:

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
