Make some guesses about how you think changes to the function rules of each of the trig functions might affect their graphs. (for example, how would a graph of sin (x−h) differ from the graph of sin⁡ x? or, how might the graph of a cos ⁡x differ from the graph of cos⁡ x? )
can someone me out?

Janet drove 300 miles in 4.5 hours. write an equation to find the rate at which she was traveling

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.
