Geometry

Question Analysis:
Tests ability to combine rotations of different directions.

Key Concept Explanation:
CCW = positive, CW = negative
Net rotation = algebraic sum
Simplify using modulo 360°

Step-by-Step Solution:
Convert to signed angles:
150° CCW = +150°
70° CW = -70°
Calculate net rotation: 150° - 70° = 80°
Result is positive → CCW

Option Analysis:
A) Correct: Net 80° CCW
B) Incorrect: Wrong direction
C) Incorrect: 360° - 80° = 280° (not relevant)
