What is the order of rotational symmetry for a rhombus

answer:

order two

Step-by-step explanation:

When we look at the above images of rhombus, it fits on to itself 2 time during a full rotation of 360 degrees.  

Hence, a rhombus has rotational symmetry of order 2.

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.
