Question

May I please get help with this math problem please I have tried so many times but still could not get the right answers

Answer 1

We know that the sum of interior angles of a triangle equals 180, then, in this case we have the following:

`90+2x+17+3x+28=180`

solving for x, we get:

`\begin{gathered} 90+2x+17+3x+28=180 \\ \Rightarrow135+5x=180 \\ \Rightarrow5x=180-135=45 \\ \Rightarrow x=(45)/(5)=9 \\ x=9 \end{gathered}`

therefore, x = 9
