I think it is
16x2+40x+25
Step-by-step explanation:
![{c}^{2} - 7c - 4 \\ {3}^{2} - (7\times 3) - 4 \\ 9 - 21 - 4 \\- 16](https://tex.z-dn.net/?f=%20%7Bc%7D%5E%7B2%7D%20%20-%207c%20-%204%20%5C%5C%20%20%7B3%7D%5E%7B2%7D%20%20-%20%287%5Ctimes%203%29%20-%204%20%5C%5C%209%20-%2021%20-%204%20%5C%5C-%2016)
Answer:
Step-by-step explanation:
arc ST is 122° , it's the same as that inner angle
arc RT ( not asked for, but needed ) is 180 °
then arc RS is 360 -180-122= RS
58= RS
Then SRT is a racing version of cars from Chrysler / Dodge :0 or also for this problem it's 180+58 =238°
