Apoint at (−8, −9) is rotated 270° counterclockwise about the origin. what are the coordinates of the resulting image?

(-9,8)

Step-by-step explanation:

A point at (−8, −9) is rotated 270° counterclockwise about the origin.

Rotation about origin with 270° counterclockwise.

Coordinate change:

Therefore,

The resulting coordinate is (-9,8)

We can also see in attachment for rotation of coordinate.

Hence, The image of coordinate after rotation 270° counterclockwise about origin is (-9,8)

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
