Geometry,
Look as we know that a triangle has three sides and three angles,
and sum of all angles has to be 180°
and a triangle can't have an angle grater than 180°.
But...
a common sense a triangle will all ways have the sum of all its angles = 180°
no matter what the condition is.
So the correct answer is, D: its equal for all three triangles.
That's it
Hope it helped (^_^メ)
