 A rhombus has order of rotational symmetry of 2

Step-by-step explanation:

We know that a geometric figure has rotational symmetry if it maps onto itself under rotation about an angle at its center.

The order of rotational symmetry is the number of times the geometric figure maps onto itself during a rotation of 360°.

[ At 180° and 360° it maps onto itself]

A  rhombus maps onto itself  two times during a rotation of 360°

Hence, A rhombus has order of rotational symmetry of 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.
