I can help you to use brainly without waiting for someone else to give you the answer.
Answer:
x = 5
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos45° =
, then
cos45° =
=
=
( cross- multiply )
x = 5
You would represent this using a linear function. You would use a linear function because it deacreases at a steady rate
