First question!!! Very simple but I don’t get it. WORTH 25 PTS

Answer:
if the bottom the RST equals 114 you judt need to subtract 114 from 72 and you get 42 :) sorry if it wrong
Step-by-step explanation:
Answer:
[tex] \boxed{\sf m\angle RSV = {42}^{ \circ}} [/tex]
Given:
[tex] \sf m\angle RST = 114^{\circ} \\ \\ \sf m\angle VST = 72^{\circ}[/tex]
To Find:
[tex] \sf m\angle RSV[/tex]
Step-by-step explanation:
[tex] \sf \implies m\angle RST = m\angle RSV + m\angle VST \\ \\ \sf \implies m\angle RSV = m\angle RST - m\angle VST \\ \\ \sf \implies m\angle RSV = {114}^{ \circ} - {72}^{ \circ} \\ \\ \sf \implies m\angle RSV = {42}^{ \circ} [/tex]
