Question

Here we go again. Tired of these yet? Obtuse triangles.

42°
84°
48°
none of these

Answer 1

none of these obtuse an obtuse triangle has sto have an angle above 90°

Answer 2

First of all, we know that the sum of interior angles in an obtuse triangle is 180

So i think <DEF would be :

180 - 84 = 96

I think the answer is : None of these

hope this helps
