Answer:
42°
Step-by-step explanation:
Since RST is 114 — a ray SV bisects RST, formimg RSV and TSV.
Since TSV is 72° and we do not know the value of RSV which I will determine it as x-term. Since the ray bisects — we have to find the value of x that adds up with 72 and get 114.
Therefore:-
The sum of RSV and TSV equals 114°
[tex] \displaystyle \large{x + 72 \degree = 114 \degree} \\ \displaystyle \large{x + 72 \degree - 72 \degree = 114 \degree - 72 \degree} \\ \displaystyle \large{x =4 2 \degree}[/tex]
