Given:

Point (7,12) is rotated 1260° counterclockwise about the origin.

To find:

The  x-coordinate of the point after this rotation.

Solution:

If a point is rotated 360 degrees then its coordinates remains unchanged.

If a point is rotated 180 counterclockwise about the origin degrees, then

(x,y)\to (-x,-y)

We know that,

1260^\circ=1080^\circ+180^\circ

1260^\circ=3\times 360^\circ+180^\circ

After 3\times 360^\circ rotation the coordinates of points remains same, i.e., (7,12). So, after that (7,12) is rotated 180° counterclockwise about the origin.

(7,12)\to (-7,-12)

The point (7,12) becomes (-7,-12) after rotation of  1260° counterclockwise about the origin.

Therefore, the x-coordinate of the required point is -7.

if a staircase rises 52° from the ground and a vertical distance of 12 yards. How much horizontal distance does the staircase co
3241004551 [841]
The horizontal distance will be found using the formula:
tan θ= opposite/adjacent
given that θ=52°
opposite= 12 yards
adjacent=x
hence
tan 52=12/x
x=12/tan 52
x=9.3754
the height is 9.375 yards
