q=45

Step-by-step explanation

Step 1

the sum of the internal angles of a triangle must be 180 , then


\begin{gathered} 3q+q+q=180 \\ \\ \\ \end{gathered}

Step 2

add similar terms


\begin{gathered} 3q+q+q=180 \\ 4q=180 \end{gathered}

Step 3

divide both sides by 4


\begin{gathered} 4q=180 \\ (4q)/(4)=(180)/(4) \\ q=45 \end{gathered}

I hope this helps you.
