ok
I need to find a
I'll find a using the Pythagorean theorem
[tex]\begin{gathered} \text{ c}^2=a^2+b^2 \\ \text{ a}^2=c^2-b^2 \end{gathered}[/tex]
Substitution
[tex]\begin{gathered} \text{ a}^2=9.5^2-7.6^2 \\ a^2\text{ = 90.25 - 57.76} \\ a^2\text{ = 32.49} \\ a\text{ = }\sqrt[]{32.49} \\ a\text{ = 5.7} \end{gathered}[/tex]
Result
a = 5.7
