With at least one of these ( i accept 1 answer if you have it; make sure you are 100% positive its correct though! )
see the attachment below. , every answer counts!

1. adjacent angles and complementary

2. vertical angles

3. supplementary angles and linear pairs

4a. right angle

4b. I'm a little confuse what they're asking for that they're epecting a word but I can give you a number which is 90 degrees. It makes the most sense but I don't know.

5. 20 degrees

6. is confusing because they're referencing two images

7.

</> (draw a horizontal line and a line in the middle. Put angles that equals to 180 in total

Sorry this isn't 100% correct but at least I tried and helped.

Step-by-step explanation:

the answer is 4.8 units on e2020.

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
