Here we go ~
Slope of the graph can be expressed as :
[tex]\qquad \sf \dashrightarrow \:slope = \tan( \theta) = \dfrac{4}{5}[/tex]
[tex]\qquad \sf \dashrightarrow \: \dfrac{x}{30} = \dfrac{4}{5} [/tex]
[tex]\qquad \sf \dashrightarrow \: x = \dfrac{4}{5} \times 30[/tex]
[tex]\qquad \sf \dashrightarrow \: x = {4}{} \times 6[/tex]
[tex]\qquad \sf \dashrightarrow \: x = 24 \: units[/tex]
So, the value of x is 24 units
