Answer:
936m
Step-by-step explanation:
What we have here is a rght triangle, where one leg is the hight between the nest and the bird (400 - 20 =380) and the other is the distance between the bird and the nest linearly from the ground (name it X). The hypotenuse is the distance the bird will fly ( name it H).
Is not clear if we need to find X or H so we will find both.
First, to find H we use the trigonometric formula:
Sin(24) = leg opposed / hypotenuse
Sin(24) is 0.406 aprox
So,
0.406 = 380/h -> h = 380/0.406 = 936 (aprox)
Then we find X, the adjacent leg to 24° using the formula:
Cos(24) = X / hypotenuse
Cos(24) is approximately 0.91
So:
0.91 = X / 936 -> X=0.91*936= 852 (aprox)
So, the distance ir 936 ir 852, depending on what you need. The statement is not very clear (however I guess it is 936 as is the distance the bird Weill fly)

Answer:
<h2>37.666 km/hr.</h2>
Step-by-step explanation:
we know the speeds in each hour were:
32 41 41
let's do
41+41+32
=113
113/3
=37.666
446,221
^
that's the tenths place
so the answer would be 446,220
Good Luck
