    The third angle is obtuse.

    Since the shape has 3 sides, then the total measure of degrees is (n-2) 180 = (3-2) 180 = 180°.

    So our equation would be

    180° = 35° + 30° + x°

    x = 115°

    115 is greater than 90, so the angle is obtuse.

    30° + 35° + x = 180°

    65° + x = 180°

    x = 115°

    The third angle is 115°. Because it is greater than 90° it is an obtuse angle.
