The method you should chose is the quadratic formula
Answer: 
Step-by-step explanation:
We see that g(x) is a straight line that passes through the origin, just like f(x), so g(x)=kx for some constant k.
Since g(x) passes through (4,2), we know that 2=4k, and thus k=1/2.
So, 
To get the answer, you need to solve the equation for x = 7.
f(7) = 3/7 + 2 - sqrt(7) - 3.
= 3/7 - 1 - sqrt(7).
If you need to simplify it further:
= -4/7 - sqrt(7).
If you need it in decimal form: = -3.2171798824

Answer:
The missing angle is 128°
Because corresponding angles are equal.
The angle pair is called <em><u>corresponding</u></em><em><u> </u></em><em><u>angles</u></em><em><u> </u></em>
