In the diagram above ML PQ and NP QR if LMN 40 ... - WAEC Mathematics 1992 Question
In the diagram above, ML//PQ and NP//QR, if ∠LMN = 40° and ∠MNP = 55°. Find ∠QPR
A
15o
B
25o
C
35o
D
40o
correct option: a
Draw line ANB// ML
< MNA = 40° (alternate angle AB/ ML)
< ANP = 55° - 40° = 15°
< POR = 15° = < ANP (corresponding angles, PN // RQ)
