First, let's find g(4). After we find it, we can substitute the value into
.
To find g(4), we need to substitute x = 4 into the function
, as shown below:



Now that we have found g(4) = 9, we can substitute this value in for
in
.



f(g(4)) is equal to 28.
Answer:
360°
Step-by-step explanation:

180° + 180° = 360°
The sum of the angles of a quadrilateral is 360°
A=a+b/2·h=9+4/2·3.5=22.75
