Answer:
z = 96
x = 33
Explanation:
Given that g and h are parallel, we can assume that 84 and z will be equal to 180.
![84 + z=180\\z= 96](https://img.qammunity.org/2022/formulas/mathematics/high-school/vgoh3rscbeup1jnc2lz2uk1fzf50fkxx38.png)
Then we make the , simple algebra work!
![96 = 6x - 102\\198 = 6x\\x = 33](https://img.qammunity.org/2022/formulas/mathematics/high-school/qiqgeuach5ewchn16fj47kqd3quegyc9na.png)
It's been like 2 years since I've touched geometry, but if I could remember I can explain this with proofs, sadly I can't.
