Question

Directions: Find the value of x.can you solve this thanks

Answer 1

Notice that all the sides of the triangle have the same measure. Then, it is an equilateral triangle. On such a triangle, all the internal angles have a measure of 60°. Then:

`4x+8=60`

Substract 8 from both sides:

`\begin{gathered} 4x+8-8=60-8 \\ \Rightarrow4x=52 \end{gathered}`

Divide both sides by 4:

`\begin{gathered} \Rightarrow(4x)/(4)=(52)/(4) \\ \Rightarrow x=13 \end{gathered}`

Therefore:

`x=13`
