Question 811964
<font face="Times New Roman" size="+2">


Measure angle 1 plus measure angle 2 = 180 by definition of supplementary.


Measure angle 1 greater than 90 by definition of obtuse.


Measure angle 2 = 180 minus measure angle 1 by addition postulate


If measure angle 1 is greater than 90, then measure angle 1 must be equal to 90 plus some real number x where x is greater than zero.  Definition of "greater than"


Measure angle 2 = 180 - (90 + x) = 90 - x where x > 0.  By substitution and the distributive property.


Measure angle 2 is less than 90 by definition of "less than"


Angle 2 is acute by definition of acute.
