We know that the trigonometric identity that uses the adjacent side and the hypotenuse is cosine. We can set this up as:

We need to solve for x, so let's isolate it:

So,
x = 10.2 units
Answer:
180m
Step-by-step explanation:
you multiply 40 by 4.5 and get 180m
1000 miles a month
12 months in a year
so 12,000 miles
divided by 4,000
simple... 3 ;)
