Consider AFGH where 2G is a right angle. Determine whether each statement is always, sometimes, or never true.
Always
Sometimes
Never
cos (1) = cos(H)
cos (F) = sin(F)
cos (F) = sin (H)
cos (H) = sin (H)

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.

well if he bought them at 5 cedis each sold them at 7 cedis each then he would make a profit of 2 cedis of each book. if in total he made 150 cedis profit that means he sold 75 books. he lost 12 books at the start so that means he originally bought a total of 82 books.
