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) Responses 77° 77 degrees 88° 88 degrees 87° 87 degrees 86°
The Triangle Angle Sum Theorem states that the sum of the three angles in a triangle is always 180 degrees.
Let's denote the third angle as x.
To find x, we can subtract the given angles from 180:
x = total sum of angles - 25° - 68°
x = 180° - 25° - 68°
x = 87°
Therefore, the third angle measures 87°.
