Question

Geometry Pythagorean theorem

Answer 1

• 6. x = 10
• 7. x = 26
• 8. x = 15

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

Answer 2

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

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
