Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

So first I would do...[tex]9x+39+12x-48=180[/tex] first because it'll give me the x value, so....

[tex]9x+39+12x-48=180\\21x-9=180\\21x=189\\x=9[/tex]

So now we know that the x equals 9 so we plug it in for (9x+39) because it's vertical to the other angle across from it and vertical angles are always congruent, so...

[tex]z=9(9)+39\\z=81+39\\z=120[/tex]

so now we know that x=9 and z=120.
