Question

Please help this is due in an hour. the equation is q+q+.3q=180 pls help.

Answer 1

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.
