Use the geometric properties and theorems you have learned to solve for x and show work PLS HELP

Step-by-step explanation:

* Knowing that they are vertical angles must mean that both angles are equal

45=3x

*divide both sides by 3

x=15

3(15)=45

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
