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.

Answer:

Well I recently tore my meniscus a little bit, but you said yours popped/locked, I don't think mine did that. But it could be a bigger meniscus tear then mine, don't take my word for it tho, I'm no orthopedic or doctor. And for the second time in 7-9 months??
