Answer:
119.8 degrees
Explanation:
While this may be a more complicated route, this is how I found the answer:
The angle above 60.2 (top left) should be equivalent to a, as they are formed from lines parallel to one another and share the other adjacent line. If we then look diagonal from the angle equivalent to a, we see the number 119.8. This is also equivalent because of the "vertical angles theorem".
Hope you pass, good luck!
