Given coordinates of the triangle: A(2,2), B(7,1) and C(8,-4).
We are given that image is rotated 90° counterclockwise about the origin.
In order to find the new coordinates of rotatation 90°counterclockwise about the origin, we can apply rule (h, k) ---> (-k,h).
Where (h,k) are the coordinates of original image on axes and (-k,h) are the coordinates of rotated image.
In resulting coordinates of the image first swap the x and y coordinates of the original image and then make the sign opposite of each x-coordinate.
On applying rule (h, k) ---> (-k,h), we get
A(2,2) --> A'(-2,2).
B(7,1) --> B'(-1,7).
C(8,-4) --> C'(4,8).
Answer:
84
Step-by-step explanation:
DCA=132° so ACB will = 180°-132°= 48°
ACB=ABC
SO ABC= 48°
To fine CAB
CAB= 180°-(ACB+ABC)
= 180°- 96
=84°
Answer:
$35.00
Step-by-step explanation:
175 x .20=35
First you would have to get them to have the same denomitator so 2 3/4 is the same as 2 6/8 but u cant subtract 1 by 6 so u move 1 8/8 over from 5 1/8 and get 4 9/8 and then u subtract and get 2 3/8
Answer:
C
Step-by-step explanation:
You can let y for the inverse
Like
X =5y - 11
Then you will get
X+11=5y
Then x+11/5=y
