Jan drew a triangle with angle measures that are 125° and 15°. What must the last degree measure be?

Any angle will work
40°
35°
25°
None of these will work.

The last angle measure must be equaled to 40 degrees because the sum of all the angles must equal to 180. So 125 + 15 + x = 180; x = 40

There is 180 degrees in a triangle, add 125 and 15 and you’ve got 140 that means there is 40 degrees left so the answer must be 40 degrees.
