Answer:

Step-by-step explanation:
All three angles in an equilateral triangle are equivalent, and they sum up to 180°, so each angle measures 60°:
60° = [8x - 44]°
+ 44° + 44°
____________
![\displaystyle \frac{104°}{8} = \frac{[8x]°}{8} \\ \\ 13° = x](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B104%C2%B0%7D%7B8%7D%20%3D%20%5Cfrac%7B%5B8x%5D%C2%B0%7D%7B8%7D%20%5C%5C%20%5C%5C%2013%C2%B0%20%3D%20x)
