See adjoining figure. Find RP and PS using the information given in ∆PSR. |

Answer» In ∆PSR, ∠S = 90°, ∠P = 30° [Given] ∴ ∠R = 60° [Remaining angle of a triangle] ∴ ∆PSR is a 30° – 60° – 90° triangle. RS = 1/2 RP [Side opposite to 30°] ∴ 6 = 1/2 RP ∴ RP = 6 × 2 = 12 units Also, PS = √3/2 RP [Side opposite to 60°] = √3/2 × 12 = 6√3 units ∴ RP = 12 units, PS = 6√3 units. |
