Use the Triangle Angle Sum Theorum to find the third angle of a triangle if the other two angles measure 25° and 68°.
The Triangle Angle Sum Theorem states that the sum of the three angles in a triangle is always 180°.
Let's say the third angle measures x°.
The sum of the three angles is equal to 25° + 68° + x° = 180°.
Combining like terms, we have 93° + x° = 180°.
To solve for x, we subtract 93° from both sides, resulting in x° = 87°.
Therefore, the third angle of the triangle measures 87°.
