Answer:
s = 55 degrees
t = 35 degrees
Explanation:
I am not sure what the question is, but I am assuming that you are trying to find the value for s and t
S and 125 are supplemental. That means that they add to 180. 180 - 125 = 55.
The two angles opposite of s together add up to 125. I know that one angle is 90, so t is 125 -90 or 35
