Answer: 40°

Step-by-step explanation:

The definition of a triangle states that the sum of its interior angles adds up to 180°. We can subtract the currently known interior angles (100° and 40°) from 180° to get our missing angle.

180° - 100° - 40°

This equation will give us the missing measure of the angle we are looking to solve.

I think it is 60 degrees if it is adding.

But, if it is subtracting, then it is still 60.

Step-by-step explanation:

Or if it is something else then it should be 40.
