X = 30
hope that helps
180 - 108 = 72
180 - 72 -43 = 65
triangle on the left
Angles = 43,65,72
triangle on the right
180 - 65 = 115
180 - 115 - 35 = 30
so angles of triangle on the right = 30, 35, 115
x = 30 (vertical angles with the other angle of triangle on the right)

20m i hope im correct if im not mb ;-;
Answer:
3rd
Step-by-step explanation:
If you know about linear eq. it's just a simple rule no worry
1/10 = .1, and 3/33 = .0909090... it is equivalent if you estimate.
The original price of phone is $ 315.76
<em><u>Solution:</u></em>
Given that Mica bought a new smart phone for $ 258.13.
That was the price after his 18.25% discount
<em><u>To find: original price of phone</u></em>
From given question,
price after discount = $ 258.13
discount = 18.25 %
Let "x" be the original price of phone
price after discount = original price - discount
![258.13 = x - 18.25 \% \text{ of } x](https://tex.z-dn.net/?f=258.13%20%3D%20x%20-%2018.25%20%5C%25%20%5Ctext%7B%20of%20%7D%20x)
![258.13 = x - \frac{18.25}{100}x](https://tex.z-dn.net/?f=258.13%20%3D%20x%20-%20%5Cfrac%7B18.25%7D%7B100%7Dx)
![258.13 = x(1 - \frac{18.25}{100})](https://tex.z-dn.net/?f=258.13%20%3D%20x%281%20-%20%5Cfrac%7B18.25%7D%7B100%7D%29)
![258.13 = x(1 - 0.1825)\\\\258.13 = x( 0.8175)\\\\x = \frac{258.13}{0.8175}\\\\x = 315.76](https://tex.z-dn.net/?f=258.13%20%3D%20x%281%20-%200.1825%29%5C%5C%5C%5C258.13%20%3D%20x%28%200.8175%29%5C%5C%5C%5Cx%20%3D%20%5Cfrac%7B258.13%7D%7B0.8175%7D%5C%5C%5C%5Cx%20%3D%20315.76)
Thus original price of phone is $ 315.76
