In triangle MPK, the lengths of three heights are known: MC = 7, PB = 9, KE = 10. Find the distance from point P to line MK.

The shortest distance from a point to a straight line is a perpendicular drawn from a point to this straight line.

The height of a triangle is also a perpendicular drawn from the vertex to the opposite side.

Then the distance from the point P to the straight line MK is the height PB = 9 cm.

Answer: From point P to straight line MK is 9 cm.
