Question

Mmhey again um yea i looked at my notes but thats not really helpful :/

Answer 1

We have the following:

Since the sides are equal, it means that all the angles are equal, we also know that the sum of the 3 angles within a triangle is always 180°, therefore

`\begin{gathered} 5x+5x+5x=180 \\ \text{solving for x:} \\ 15x=180 \\ x=(180)/(15) \\ x=12 \end{gathered}`

The value of x is 12
