Answer:

8=58.5°

9= 125°

10= 55°

Step-by-step explanation:

8.) 31.5 + 90 = 121.5 - 180 = 58.5°

9.) 25 + 30 = 55 - 180 = 125°

10.) 45 + 80 = 125 - 180 = 55°

Answer:

X= 11

Step-by-step explanation:

That equation becomes -7x+15x-30 =58

And add them all up giving you 8x-30=58

Add 30 to both sides

8x=88

Divide 88 by 8 which gives you 11

Answer: Second Option

$f (x)=\frac{2}{x}$ and $g(x)=\frac{2}{x}$

Step-by-step explanation:

If we have a function f(x) and its inverse function $f ^ {- 1} (x) = g (x)$

Then by definition:

$(fog) (x) = (gof) (x) = x$

Notice that the inverse of the function $f (x)=\frac{2}{x}$ is $f ^ {- 1}(x)=\frac{2}{x}$

then:

If $f (x)=\frac{2}{x}$ and $g(x)=\frac{2}{x}$

Then:

$(fog) (x) =\frac{2}{\frac{2}{x}}$

$(fog) (x) =\frac{2x}{2}$

$(fog) (x) =x$

The answer is the second option
