If you need me to clarify anything i got you
This should be what you need, sorry for the wonky lines.
Answer:

Step-by-step explanation:
If the graph of the function
represents the transformations made to the graph of
then, by definition:
If
the graph is stretched horizontally by a factor 
If
the graph is compressed horizontally by a factor 
In this problem we have the parent function
And we know that it stretches horizontally by a factor of 4
Therefore
and 
The transformation is:
And the function is:

Ok this one is easier than you might think. The line equals 180 degrees since it is a straight line, therefore you need to do 180-27 to get what y equals. Y=153
U can put any 2 angles that form a straight line ( example: C & B )
