Answer:

6. x = 10 ,  7. x =26   ,  8. x = 15

Step-by-step explanation:

Using Pythagoras theorem,

6)

x² = 8² + 6²

x = √64+36

x = √100

x = 10

7)

x² = 24² + 10²

x = √576+100

x = √676

x = 26

8)

x² = 9² + 12²

x = √81 + 144

x = √225

x = 15

Answer:

  • 6. x = 10
  • 7. x = 26
  • 8. x = 15

Step-by-step explanation:

Question 6:

  • x² = 8² + 6²
  • => x² = 64 + 36
  • => x² = 100
  • => x = 10

Question 7:

  • x² = 24² + 10²
  • => x² = 576 + 100
  • => x² = 676
  • => x = 26

Question 8:

  • x² = 12² + 9²
  • => x² = 144 + 81
  • => x² = 225
  • => x = 15
