Answer:
190 degrees
Step-by-step explanation:
let's ignore the 10 degrees first. you see the half circle with the angle on it, that is called a supplementary angle. all supplementary angles are equal to 180 degrees. so we know that that is already 180 degrees, then you have to add back the 10 degrees to get the full angle. so you add 10 to 180 and get 190 degrees.
