Answer:
[tex]79[/tex]°
Step-by-step explanation:
we know from the question that [tex]STV[/tex]is equal to [tex]85[/tex]°, it is also given that [tex]VTU[/tex] is [tex]6[/tex]°
to find [tex]STU[/tex] subtract [tex]STV =85[/tex]° from [tex]UTV=6[/tex]°
[tex]STV-UTV=STU\\[/tex]
[tex]85[/tex]°[tex]-6[/tex]°[tex]= 79[/tex]°
So [tex]STU[/tex][tex]=79[/tex]°
