Answer:

x = 5.1

Step-by-step explanation.

Our first step is to find all the angles. If b = 91 degree and c is 38, a. has to be 51 because all triangles add up to 180 degree. Because we have both B and b, we can use sine law.

a/A 13/sin91 c/38

we can use b in this situation.

The legnth of a is 10.1.

So, x-5 would be 5.1

I have to record myself answering questions for my math class and I really need help. I will reward 36 points.

Answer:

If the two graphs are symmetric with respect to the line y = x (mirror images over y = x ), then they are inverse functions. But, we need a way to check without the graphs, because we won't always know what the graphs look like! then f(x) and g(x) are inverse functions.

Step-by-step explanation: Hope this helps :)
