Hell I need help with a couple problems they are test grades

Line T is parallel to Line V and they are cut by a transversal line R. Thus, corresponding angles are equal;
[tex]4x-24=3x[/tex]Then;
[tex]\begin{gathered} 4x-3x=24 \\ x=24^o \end{gathered}[/tex]But measured angle RST is;
[tex]\begin{gathered} m\angle RST=3x \\ m\angle RST=3(24) \\ m\angle RST=72^o \end{gathered}[/tex]
