From the diagram it can be wrriten as,
[tex]2x+5+3x+10=90[/tex]Simplify the expression and find the value of x.
[tex]\begin{gathered} 5x+15=90 \\ 5x=90-15 \\ x=15 \end{gathered}[/tex]Put 15 for x in the expression 2x+5 gives,
[tex](2\times15)+5=35^0[/tex]Put 15 for x in the expression 3x+10 implies,
[tex](3\times15)+10=55[/tex]Therefore,
[tex]\begin{gathered} x=15^0 \\ 2x+5=35 \\ 3x+10=55 \end{gathered}[/tex]
