Question

Identify two statements that contradict each other.

I. ∠M is an obtuse angle.

II. m∠M + m∠P = 90

III. 180 − m∠M = 25

IV. m∠P = 120

1. 
   
2. A.=I and II

B=I and IV

C=I and III

D.=III and IV

Answer 1

Obtuse angles are greater than 90 degrees, so any angle summed with an obtuse angle will be greater than 90 degrees, so I and II are contradictory (A).
