R/s^5t^r2st-2/r^3
hope this helps
The answer is B
Cause they all have the same angle points
Answer:
=> equation 1
=> equation 2
=> equation 3
Step-by-step explanation:
Points P, Q, R, S, and T are collinear therefore, the following equations can be written based on the segment addition postulate:
=> equation 1
=> equation 2
=> equation 3
More equations can actually be written from the diagram given using the segment addition postulate. Such as:

1700 and 2550
You might want to double check that. I'm not certain.
