In the figure given above (PQ parallel to RS; transversal QR making 55° with PQ; at R, RL makes 30° with RQ and 25° with RS; LM drawn from L on RL with 155° above), PQ is parallel to RS. What is the angle between the lines PQ and LM ?
Elementary MathematicsGeometry
- A175°
- B177″
- C179″
- D180°
Explanation
LM is horizontal (180°-25°=155° checks), hence parallel to PQ; angle = 180°.
