What will be the new position of the point (−8, 4) when rotated through 90° anti- clockwise about the origin?

i. (−4, −8) ii. (−4, 8) iii. (4, 8) iv. (2, 4)

we have

(x,y). rotation through 90° anti-

clockwise about the origin(-y,x)

point (−8, 4) when rotated through 90° anti-

clockwise about the origin(-4,-8)

Option.i. (−4, −8)

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
