To find the third angle of a triangle, we use the Triangle Angle Sum Theorem, which states that the sum of the angles in a triangle is always 180°.
25° + 68° + x = 180°
93° + x = 180°
x = 87°
Therefore, the third angle of the triangle is 87°.
Use the Triangle Angle Sum Theorem to find the third angle of a triangle if the other two angles measure 25° and 68° . (1 point)
