Answer:
QRT = 47, TRS = 133
Step-by-step explanation:
Since QRS is a line, QRT + TRS = 180.
![QRT+TRS=180\\3x+5+10x-7=180\\](https://tex.z-dn.net/?f=QRT%2BTRS%3D180%5C%5C3x%2B5%2B10x-7%3D180%5C%5C)
Then, solve for x. Combine like terms.
![13x-2=180\\13x=182\\x=14](https://tex.z-dn.net/?f=13x-2%3D180%5C%5C13x%3D182%5C%5Cx%3D14)
Then, plug in 14 for x.
![1. (3*14+5)\\\\QRT = 47\\\\2. (10*14-7)\\\\TRS = 133](https://tex.z-dn.net/?f=1.%20%283%2A14%2B5%29%5C%5C%5C%5CQRT%20%3D%2047%5C%5C%5C%5C2.%20%2810%2A14-7%29%5C%5C%5C%5CTRS%20%3D%20133)
The answer is going to 25.13
