Answer:
I cannot show work because I did it in my brain but the answer is 122 degrees.
Explanation:
Since QOR is 122 degrees and TOS is the same thing as QOR they will have the same value. Therefore our answer is 122.
Hope this helps :
<TOS = 122
<QOR = <TOS because of vertical angles theorem
<QOR = 122
That makes <TOS = 122
