3 angles add to 180
the first two add to 100
the third is 180-100 or 80 degrees

+15+%2B+85+=+100+ degrees
The sum of the angles is +180+ degrees
+180+-+100+=+80+
The 3rd angle is 80 degrees

All of the interior angles of a triangle add up to 180°
Therefore we can take the two measurements we have and subtract them from 180° to get the final:
180-15-85
=80
Therefore the angles of the triangle are:
80° 15° and 85°
