To find the measure of the third angle in a triangle, we use the fact that the sum of the angles in a triangle is always 180°.

Given the angles are 30° and 85°, we can calculate the third angle as follows:

\[
\text{Third angle} = 180° - (30° + 85°)
\]

\[
\text{Third angle} = 180° - 115°
\]

\[
\text{Third angle} = 65°
\]

Therefore, the measure of the third angle is **65°**.
