Answer :

  • x = 15

Explanation :

the formula to find the length of the altitude of a right angled triangle is

  • x = √ab

here ,

  • a = 9
  • b = 25

plug in,

  • x = √(9*25)
  • x = 15

____

using the similar triangles theorem,

  • 9/x = x/25
  • x^2 = 9*25
  • x^2 = 225
  • x = √225
  • x = 15
