Geometry

Question Analysis:
This question tests the application of the Law of Detachment to geometric properties of angles.
The main focus is on determining the type of angle based on its measure.

Key Concept Explanation:
The Law of Detachment allows us to conclude that if a condition (P) is met, then the result (Q) must follow.

Step-by-Step Solution:
The conditional statement is: "If an angle is acute, then it measures less than 90 degrees."
The premise is: "Angle B measures 85 degrees."
Since 85° < 90°, Angle B is acute.

Option Analysis:
A) Correct. Angle B is acute because it measures less than 90 degrees.
B) Incorrect. A right angle measures exactly 90 degrees.
C) Incorre...
