(iv) the distance of the point ( 0 , -3 ) from the origin is ……. units

The distance is 3

Step-by-step explanation:

It can be demonstrated that the distance is 3 by performing the operation to obtain the distance between two points.

Where (x2,y2)=(0,0) since it is the origin.

(x1,y1)=(0,-3)

We can see that = 0

And that = 9

Hence the distance is 3

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
