Find the measure of the exterior angle.

52 degrees

Step-by-step explanation:

both degrees have to equal 9 because it is a right angle. so subtract 90 and 38 to get your answer.

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
