Answer:
(0,-8)
Step-by-step explanation:
90° rotation (x,y) > (-y,x)
180° rotation (x,y) > (-x,-y)
270° rotation (x,y) > (y,-x)
Answer:
I'm not entirely sure but I think that what is says is that it wants you to find the value of x in (4x+28) to make it 116 degrees because it is that same angle. So what you do is you get (4x+28)=116 and you do this because they are the same angle so you use 116 and get it to solve x. Since I'm lazy, then I go to this website and type the equation in: m a t h w a y . c o m but without all of the spaces, I had to do that so it would let me answer this, but I'll do it the real way this time. (4x+28)=116 Their is a rule in math that as long as you do something to one side of the equal sign in the equation, you have to do it to the other and it will still work. So, you minus 28 from both sides so that you can get rid of it and you now have 4x=88. Now you should know this part but you divide 4 from both sides to make so x is alone. Now you have x=22 because you divided 4 from each side. So their is your answer: x=22.
Step-by-step explanation: If you have the answer key that you can check from to make sure you got it right because I know some teachers let you do that, then you should make sure that is right, but I am pretty sure it is.
The next step she should take is to use her ruler to join the given point to the point where the arcs intersect.
<h3>Steps in constructing perpendicular lines</h3>
- Place your compass on the given point
- Draw an arc across the line on each side of the given point. Do not adjust the compass width when drawing the second arc
- From each arc on the line, draw another arc on the opposite side of the line from the given point. The two new arcs will intersect.
- Use your ruler to join the given point to the point where the arcs intersect.
- Use your compass and ruler to draw a perpendicular line from each given point to the line segment
From this, we can deduce that her next step is to use her ruler to join the given point to the point where the arcs intersect
Thus, the next step she should take is to use her ruler to join the given point to the point where the arcs intersect.

-2, I’m guessing, but yes try that and if it doesn’t help text me again
2.2 i think because 12 divided by 5 2/5 = 12 divided by 5/27 = 2.2
