Question

HII EVERYONE....

GOOD EVENING

Coordinates of th point P ( x,y ) , where x, y >0 . If line segment OP is making angle 45° with positive x - axis , thrn what angle should OP be rotated so as to make x and y both negative ?

PlZZ GIVE ME ANSWER....

Answer 1

Answer:

actually there is no exact answer of it

answer must in range

if we rotate the coordinates greater than 135° and less than 225°

then x ,y are always negative

Answer 2

Answer:

Step-by-step explanation:

As we know OP is making angle of 45°

So we need to tilt it to bring it from 1st quadrant to 3rd quadrant (as asked in the question).

The y axis is making 180°.

So, 180°-45°=135°

And the 3rd quadrant lasts till 180°+90°(x' axis)= 270°

And now subtracting 270°- OP=

270°-45°=225°

So to make X and y negative it can be any angle between 135° and 225°.

Hence, 135°<(any angle)<225°.

Hope it helps...
