find the exact length of the third side

Answer:
The third side is equal to 85
Step-by-step explanation:
Step 1: Use Pythagorean Theorem
[tex]a^2 + b^2 = c^2[/tex]
[tex](68)^2 + (51)^2 = c^2[/tex]
[tex]4624 + 2601 = c^2[/tex]
[tex]7225 = c^2[/tex]
[tex]\sqrt{7225} = \sqrt{c^2}[/tex]
[tex]85 = c[/tex]
Answer: The third side is equal to 85
Answer: 85
Step-by-step explanation:
a squared plus b squared equals c squared
68^2 + 51^2 =c^2
7225=c^2
take the square root of 7225 and you get 85
