To find the third angle of a triangle, we can use the Triangle Angle Sum Theorem, which states that the sum of the measures of the three angles in a triangle is always 180°.
Let's call the third angle x.
According to the Triangle Angle Sum Theorem, we have the equation:
25° + 68° + x = 180°
Combining like terms, we get:
93° + x = 180°
To isolate x, we subtract 93° from both sides of the equation:
x = 180° - 93°
x = 87°
Therefore, the third angle of the triangle measures 87°.
Use the Triangle Angle Sum Theorem to find the third angle of a triangle if the other two angles measure 25° and 68
