Question 254506: Find the acute angle A, to the nearest second, when:
A. log cos A = 9.12575
B. log sin A = 9.91655
C. log cot A = 0.11975
D. log tan A = 0.06323 Answer by Alan3354(69443) (Show Source):
You can put this solution on YOUR website! Find the acute angle A, to the nearest second, when:
A. log cos A = 9.12575
cos(A) =~ 1335826332
The cosine is >1, there's no real number solution.
-------------------
B. log sin A = 9.91655
Same here.
-----------
C. log cot A = 0.11975
cot(A) = 1.317498...
A = 37.199 degs
A = 37º 11' 56" (principal value)
--------------
D. log tan A = 0.06323
tan(A) = 1.1567...
A = ~ 49.156º
A =~ 49º 9' 23" (principal value)
