Answer 3

Oh, I see what it is now. Tell me this....is ECD obtuse or acute?

Answer 4

obtuse

Answer 5

Exactly. So what would be the most likely choice for the correct angle?

Answer 6

By process of elimination...

Answer 7

obtuse

Answer 8

Yes, but which of the answer choice would be the correct one?

Answer 9

131

Answer 10

Excellent. Because it's obtuse, we know that 49 and 41 are automatically eliminated. Angle 180 degrees can only be a straight line. So therefore, the only other obvious choice is 131.
