Step-by-step explanation:
![f(3) = {(3)}^{2} + 3(3) - 7 = 9 + 9 - 7 \\ = 18 - 7 = 11](https://tex.z-dn.net/?f=f%283%29%20%3D%20%20%7B%283%29%7D%5E%7B2%7D%20%20%2B%203%283%29%20-%207%20%3D%209%20%2B%209%20-%207%20%5C%5C%20%20%3D%2018%20-%20%207%20%3D%2011)
![g(3) = 5(3) - 3 = 15 - 3 = 12](https://tex.z-dn.net/?f=g%283%29%20%3D%205%283%29%20-%203%20%3D%2015%20-%203%20%3D%2012)
![f(3) + g(3) = 11 + 12 = 23](https://tex.z-dn.net/?f=f%283%29%20%2B%20g%283%29%20%3D%2011%20%2B%2012%20%3D%2023)

2x+50 + 3x= 90 degrees
5x +50 = 90
5x =40
x=8
Angle1= 2(8) +50= 66
Angle2= 3(8)=24
66+24+90= 180
you answer is 10 hope this help[s :D
