It would be b because if you take 10 and shusbejsjdhebe
Positive 25 that's the answer
In this problem you use cosine because you know the hypotenuse and you want to know the adjacent side of the triangle. So in your calculator you would input cos(52). Then you would multiply that answer with the hypotenuse side. So your equation would be this: cos(52) x 13
The idea is to use the tangent line to 
at 
in order to approximate 
.
We have
so the linear approximation to 
is
Hence 
and 
.
Then
Answer:
Gradient is = 0.375
Step-by-step explanation:
Rise = 3
Run = 8
