can someone please explain this and how to do these types of problems??!?! im so confused and i dont know how to do them right

28/53

Step-by-step explanation:

We need the cos of Q

therefore we'll use CAH (in SOH, CAH, TOA)

where CAH means

cos(angle)=adj/hyp

the side that adjacent to Q is 28

and the hypotonous (the oppsoite to the right angle) is 53

therefore cos(q)=28/53

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
