What are the angles of a triangle with side lengths of 9.66, 12, and 15.4. one of the angles is 90 degrees.

you need to add a picture

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
