Point H is the base of the height drawn from the vertex of the right angle B of triangle ABC to the hypotenuse AC. Find AB if AH = 6, AC = 24.

Consider the triangles ABC and ABH.
∠A – general
Therefore, these triangles are similar (by similarity)
Then AC / AB = AB / AH (the hypotenuse of the large triangle refers to the hypotenuse of the small as the small leg of the large triangle to the small leg of the small triangle)
24 / AB = AB / 6
24 * 6 = AB ^ 2
144 = AB ^ 2
AB = 12
Answer: AB = 12

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
