Find x in this 45°-45°-90° triangle.

x =

The answer to your question is x = 11√2  or 15.56  

Step-by-step explanation:

Data

Right triangle

hypotenuse = 22

angle = 45°

adjacent side = 45°

To solve this problem, use trigonometric functions. The trigonometric function that relates the adjacent side and the hypotenuse is cosine.

                   cos Ф = Adjacent side / hypotenuse

-Solve for adjacent side

                  Adjacent side = hypotenuse x cos Ф

-Find cos 45° = √2 / 2

-Substitution

                 Adjacent side = (22)(√2 /2)

                Adjacent side = 11√2  or 15.56  

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.

the answer would be c:   ax + b = ax + c
