Respuesta :
When you have supplementary angles they will add up to a sum of 180 degrees. So if you have one of the measure measurements then subtract that from 180.
Anyone feel free to correct me if you think I'm wrong:
If it already gives the measure for one of the angles subtract it from 180 since it is supplementary. If both angles are right angles, they equal 90.
Hope it helps.
