Application +4 | -1

If a line joining two points

A(2,0)

and

B(3,1)

is rotaled about

A

in anticlockwise direction through an angle

15^{\circ}

such that the point

B

goes to

C

in the new position, then the coordinates of

C

are

View answer and explanation

Correct option: D

\left(2-\frac{1}{\sqrt{2}},-\frac{\sqrt{3}}{2}\right)

Option D

\left(2-\frac{1}{\sqrt{2}},-\frac{\sqrt{3}}{2}\right)

is correct because it represents the coordinates of the point C after rotating point B about A by 15 degrees in the anticlockwise direction.
