A triangle has an angle that is 83 degrees and another angle that is 40 degrees. Using this information, what is the degree of the third angle of the triangle?

180 - 83 - 40 = ?

A triangles angles equal to 180 degrees. So add the two angles that you have up and subtract it from 180.

To find the degree of the third angle of a triangle, you can use the fact that the sum of all angles in a triangle is always 180 degrees.

In this case, you are given two angles: 83 degrees and 40 degrees. To find the third angle, subtract the sum of the two given angles from 180.

The calculation would be:

180 - (83 + 40) = 57 degrees.

Therefore, the degree of the third angle of the triangle is 57 degrees.
