In this problem you will use a ruler to estimate the length of JK. Afterwards you will be able to see the lengths of the other two sides and you will use the pythagorean theorem to check your answer



Answer :

ok

[tex]\begin{gathered} \text{ JI}^2=JI^2-KI^2 \\ JK^2=8.1^2-3.8^2 \\ JK^2\text{ = 65.61 - 14.44} \\ JK^2\text{ = 51.57} \\ JK\text{ = 7.15 cm} \end{gathered}[/tex]

JK = 7.15 cm
