Answer:
![x=20\°](https://tex.z-dn.net/?f=x%3D20%5C%C2%B0)
Step-by-step explanation:
Given:
Angles of triangle: 105° and 55°
is the missing angle of the triangle.
We know that sum of all three angles of a triangle =180°
∴ ![x+105\° +55\° =180\°](https://tex.z-dn.net/?f=x%2B105%5C%C2%B0%20%2B55%5C%C2%B0%20%3D180%5C%C2%B0)
![x+160\° =180\°](https://tex.z-dn.net/?f=x%2B160%5C%C2%B0%20%3D180%5C%C2%B0)
Subtracting 160° from both sides.
![x+160\°-160\° =180\°-160\°](https://tex.z-dn.net/?f=x%2B160%5C%C2%B0-160%5C%C2%B0%20%3D180%5C%C2%B0-160%5C%C2%B0%20)
∴ ![x=20\°](https://tex.z-dn.net/?f=x%3D20%5C%C2%B0)
