Triangle WXY, with a vertex ∠X at (3, 0), is rotated clockwise 90° about the origin. Which of the following rotations is equivalent to 90° clockwise rotation about the origin?

A. clockwise 270°
B. counterclockwise 270°
C. counterclockwise 90°
D. clockwise 360°

Respuesta :

B.) counterclockwise 270°

We know, In order to change the nature of rotation, we have to subtract the angle from 360 degrees.
So, 360 - 90 = 270 [ & don't forget to change clockwise to counterclockwise ]

Hope this helps!
B. counterclockwise 270°
