Question

What is the value of x? show all the work

Answer 1

9 cm

Explanation:

Using pythagoras theorem

(Sqrt(117))² = 6² + x²

117 = 36 + x²

x² = 81

x = 9

Answer 2

9 cm

Explanation:

You can use the pythagorean theorem to find x here. Since
`AB^2 + BC^2=AC^2, AC^2-BC^2=AB^2`.
`\sqrt{√(117)^2-6^2}=√(117-36)=√(81)=9`. Hope this helps!
