To find the measure of the third angle of the triangle, we can use the Triangle Angle Sum Theorem, which states that the sum of the angles in a triangle is always 180°.

Let's call the measure of the third angle x°.

According to the Triangle Angle Sum Theorem, we have:

34.6° + 52.8° + x° = 180°

Combine the known angles:

87.4° + x° = 180°

Subtract 87.4° from both sides:

x° = 180° - 87.4°

x° = 92.6°

Therefore, the measure of the third angle of the triangle is 92.6°.
