I don’t know if i’m right or wrong but i calculate the answer & go 0.05
Change the - to sum
x+-2y=8
The second one to the opposite
And x is 2 and y is 2 so
It’s 2+2 is 4 and 4 multiplied by 2 is 8
I hope I am correct, good luck! :)
The values of CotD and SinC from the information given in the task content are; 15/8 and 15/17 respectively.
<h3>What is the value of cotD and sinC?</h3>
It follows from the task content that the right triangle has tanC = 15/8 and cosD=15/17.
On this note, it follows from Pythagoras theorem that the other value are as follows;
- sinC = 15/17, cosC = 8/17
- sinD = 8/17 and tanD = 8/15
Hence, it follows that the values of cotD and sinC are; 15/8 and 15/17 respectively.

Answer:
The answer is rotation 270° about the origin
Step-by-step explanation:
If (x , y) is a point in xy-coordinates
If the point rotate about the origin ⇒ (The positive direction is anti-clockwise)
1- 90°
Its image is (-y , x)
2- 180°
Its image is (-x , -y)
3- 270°
Its image is (y , -x)
If we assume A is (1 , 7)
1- ⇒ (-7 , 1) ⇒ rotation 90° about the origin
2- ⇒ (-1 , -7) ⇒ rotation 180° about the origin
3- ⇒ (7 , -1) ⇒ rotation 270° about the origin
∵ x-coordinate of point A small and +ve and y-coordinate large and +ve
∵ x-coordinate of point A' large and +ve and y-coordinate small and -ve
∴ The answer is rotation 270° about the origin
∴ The answer is rotation 270° about the origin
