  PJ ⊥ KP

Step-by-step explanation:

The little square corner at point P is the mark that indicates lines are perpendicular.

That is the only on mark indicating perpendicular in this diagram. It shows line KI to be perpendicular to line MJ. Then all of the segments on one of those lines are perpendicular to any of the segments on the other of those two lines.

Just to make sure we don't get in trouble with interpretation, we should probably include point P in any segments we list.

  MJ ⊥ KI

  OJ ⊥ KI

  MP ⊥ KI

  OP ⊥ KI

  PJ ⊥ KI

In any of the above, KI can be replaced by KP or PI and the statement will remain true.

Additional comment

Segment NI, being parallel to OP, is also perpendicular to KI. However, it is not marked as such.

MO is perpendicular to PI, but isn't really marked as such.

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

answer is 144
