In the diagram, PQ is parallel to RS, ∠QFG = 105° and ∠FEG = 50°. Find the value of n
- A. 40°
- B. 55°
- C. 75°
- D. 130°
Correct Answer: C. 75°
Explanation
E\(G\)R = 50\(^o\) (Alternative angles)
n + 55\(^o\) + 50\(^o\) = 180\(^o\) (Sum of angles on a straight line)
n = 180\(^o\) - 105\(^o\)
n = 75\(^o\)
