Triangles are shapes with three sides and angles
The value of B is 16.3 degrees
<h3>How to determine the value of B</h3>
The given parameters are:
a = 64
b = 18
c = 63
Next, we apply the following cosine formula
So, we have:
Evaluate the exponents
Collect like terms
Solve for cos (B)
Take the arccos of both sides
Hence, the value of B is 16.3 degrees
