The diagram is given with two angles.
[tex]3x\degree,(2x+5)\degree[/tex]To find the value of x.
From the diagram , the sum of the angles is 180 degree.
[tex]\begin{gathered} 3x\degree+2x+5\degree=180\degree \\ 5x=180\degree-5\degree \\ 5x=175\degree \\ x=35\degree \end{gathered}[/tex]Hence the value of x is
[tex]35\degree[/tex]
