What is the measure of the angles? 145° 35° 13° 180°

35° is your answer.

Step-by-step explanation:

These are vertical angles. Set the two measurements equal to each other and solve for x.

3x - 4 = 2x + 9

Isolate the variable (x). Note the equal sign, what you do to one side you do to the other. Add 4 and subtract 2x from both sides.

3x (-2x) - 4 (+4) = 2x (-2x) + 9 (+4)

3x - 2x = 9 + 4

x = 13

Plug in 13 for x in one of the measurements given.

2x + 9

2(13) + 9

26 + 9

35

35° is your answer.

The measure of the angle is 35

Step-by-step explanation:

The angles are vertical angles which means they are equal

3x-4 = 2x+9

Subtract 2x from each side

3x-4 -2x =2x+9-2x

x-4 = 9

Add 4 to each side

x-4+4 =9+4

x=13

But we want to know the angle

2x+9

2(13)+9

26+9

35

The measure of the angle is 35

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.
