Sides of triangle

Triangle circumference with two identical sides is 117cm. The third side measures 44cm. How many cms do you measure one of the same sides?

Correct answer:

x =  36.5 cm

Step-by-step explanation:

$$\begin{gathered} o=117\text{ cm } \\ c=44\text{ cm } \\ x=(o-c)\mathrm{/}2=(117-44)\mathrm{/}2=36.5\text{ cm} \end{gathered}$$
