The height of the tide after eight hours is 16 feet.
<h3>How to illustrate the function?</h3>
From the information given, the function is given as 5cos (π/4)t + 11.
In this case, the time is given as eight hours. This will be:
f(8) = 5 × cos (π/4) × 8 + 11
f(8) = 5 × cos(2π) + 11
= (5 × 0.999) + 11
= 16 feet
The height is 16 feet.

Answer: angle B = 15.04104216 degrees approximately
Round that however you need to.
============================================================
Explanation:
The lowercase letters a,b,c are used as side lengths while the uppercase letters A,B,C are the angles.
- Side 'a' is opposite angle A
- Side b is opposite angle B
- Side c is opposite angle c
From the diagram, we have the following info:
- side b = 22
- side c = 63
- side C = 48
Use the law of sines to find B
sin(B)/b = sin(C)/c
sin(B)/22 = sin(48)/63
sin(B) = 22*sin(48)/63
sin(B) = 0.25951089143656
B = arcsin(0.25951089143656)
B = 15.04104216 which is approximate
------------------
Another possible value of B is
B = 180-arcsin(0.25951089143656) = 164.95896
Since
sin(15.04104216) = sin(164.95896) = 0.2595109
However, notice that this leads to
A+B+C = 180
A+ 164.95896 + 48 = 180
A + 212.95896 = 180
A = 180 - 212.95896
A = -32.95896
But we cannot have a negative angle. Therefore only one triangle is possible here.
The only solution is approximately B = 15.04104216
