Answer:

7√3

Step-by-step explanation:

Pythagorean Theorem

a² + b² = c²

7² + b² = 14²

b² = 14² - 7²

b² = 196 - 49

b = √147

Answer:

[tex]AC = 12.12[/tex]

Step-by-step explanation:

Step 1:  Determine side AC

[tex]Pythagorean\ theorem[/tex] → [tex]a^2 + b^2 = c^2[/tex]

[tex](AC)^2 + (CB)^2 = (AB)^2[/tex]

[tex](AC)^2 + (7)^2 = (14)^2[/tex]

[tex](AC)^2 + 49 = 196[/tex]

Step 2:  Subtract 49 from both sides

[tex](AC)^2 + 49 - 49 = 196- 49[/tex]

[tex](AC)^2 = 147[/tex]

Step 3:  Square root both sides

[tex]\sqrt{(AC)^2} = \sqrt{147}[/tex]

[tex]AC = 12.12[/tex]

Answer:  [tex]AC = 12.12[/tex]
