Answer:
LBC is 75 degrees
Step-by-step explanation:
When you follow the angle measurements from the first and when one line equals 180, figuring out the other angle measurements can determine the answer for LBC.

True
Note that:
The graph of sine and cosine functions are very similar. They only have a shift in the x -axis.
That is, sin x = cos (90 - x)
Since there is a great similarity between the sine and cosine graphs, and the secant graph is an inverse of the cosine graph, the graph of sine can be used to construct the graph of the secant function
Mathematically:
since sec x = 1 / cos x
and, cos x = sin (90 - x)
therefore, sec x = 1 / sin (90 - x)
The graphs of the sine and secant functions are attached to this solution

Set up a proportion
3/7/12 = 1/x
3/7x = 12
x = 28
28 - 12 = 16
16 are left
