The points of (9,1) after a 270 degree counterclockwise rotation would be (1,-9)
Hope this helps!
All 3 angles of a triangle must equal to 180. You can simply set up an equation to solve this and set it equal to 180.
Angle 1 - 50 + x
Angle 2 - x
Angle 3 - 2x -10
50+x+x+2x-10=180
4x+40=180
4x=140
x=35
Angle 1 = 50+35= 85
Angle 2 = 35
Angle 3 = 2(35) - 10 = 60
60+35+85=180
Answer:
The new points or new image would (-2, 2)
Step-by-step explanation:
Basically DILATION means to make the image smaller or bigger depends on the points. So, I did was I multiplied -8 by 1/4 which gave me -2 and then I multiplied 8 by 1/4 which gave me 2!
