Answer:
The length of the third side is [tex]≈15.7[/tex]
Step-by-step explanation:
Note:
Phitagors theorem:
[tex]c^{2}=a^{2}+b^{2}[/tex]
[tex]c: hypotenuse[/tex]
[tex]a: altitude[/tex]
[tex]b: base[/tex]
1) Using Phitagors theorem
[tex]c^{2}=a^{2}+b^{2}[/tex]
[tex]c^{2}=14^{2}+7^{2}[/tex]
2) Calculate
[tex]c^{2}=245[/tex]
3) Take the square root of both sides of the equation
[tex]\sqrt {c^{2}}=\sqrt{245}[/tex]
[tex]c=\sqrt{245}[/tex]
[tex]c≈15.7[/tex]
