Step-by-step explanation:
When we read this example we can see that Peter will form triangle with those sides :
a=200 m,
b=180 m
cos X=cos (180-105)=cos75
x is angle.
Now, we can use this rule :
Now, let's evaluate :
Answer:
None of the above.
Step-by-step explanation:
Let us check each of the answer choices one bye one.
Choice A:
solving for y we get:
which is not equal to our function h(x).
Choice B: .
This gives
which is not equal to our function h(x).
Choice C: and
.
The first expression does not contain y, thus it is not equivalent to h(x). The second equation already gives the value of y , and we see that it is not equal to h(x).
Therefore we conclude that none of the choices given are correct.
