Answer:

option c. ±[tex] \sqrt{65} [/tex]

Step-by-step explanation:

In the given right angled triangle we can see that :-

  • hypotenuse is 9
  • adjacent is 4
  • opposite is x

by Pythagoras theorem

hypotenuse² = adjacent ² + opposite ²

9² = 4² + x²

81 = 16 + x²

combining like terms

81 - 16 = x²

65 = x²

x = ±[tex] \sqrt{65} [/tex]
