Determine the positive angle that would correspond to a rotation of -90 degrees. Explain your answer.

270 degrees

a right angle because 190 degree is a right triangle so find the coralation and simplify answer determine value and round to the nearest tenth degree

To determine the positive angle that corresponds to a rotation of -90 degrees, we need to understand the concept of rotational direction and how angles are measured.

In trigonometry, angles are typically measured counterclockwise from the positive x-axis. This is known as the positive direction of rotation. However, angles can also be measured in the clockwise direction, known as the negative direction of rotation.

In this case, a rotation of -90 degrees indicates a rotation in the negative direction, or clockwise, by an angle of 90 degrees. To find the positive angle that corresponds to this rotation, we need to add 360 degrees to the given negative angle.

-90 degrees + 360 degrees = 270 degrees

Therefore, a rotation of -90 degrees is equivalent to a positive rotation of 270 degrees.
