Your friend says that there is an angle whose measure is the same as the measure of the sum of its supplement and its complement.

Is your friend correct? What is the measure of the angle?

, the measure of its complement is

, and the measure of its

The measure of the angle is

supplement is

The angle is 90°

Supplement of angle = 90°

Complement of angle = 0°

Step-by-step explanation:

Let the angle be y

Supplement of angle = 180 - y

Complement of angle = 90 - y

Since measure of angle equals sum of it's complement and it's supplement, therefore;

180 - y + 90 - y = y

270 - 2y = y

270 = 3y

y = 270/3

y = 90°

Therefore the angle is 90°

Supplement of angle = 180 - 90 = 90°

Complement of angle = 90 - 90 = 0°

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.

other answer is correct. i had used the radius of the radius somehow. a website:
