Solution

(i) Sin P = `" Opposite side of ∠P"/" Hypotenuse "` = `["QR"]/["PQ"]`

(ii) CosQ = `"Adjacent side of ∠Q"/" Hypotenuse "` = `["QR"]/["PQ"]`

(iii) tan P = `" Opposite side of ∠P"/"Adjacent side of ∠P"` = `["QR"]/["PR"]`

(iv) tan Q = `" Opposite side of ∠P"/"Adjacent side of ∠P"` = `["PR "]/["QR"]`

  Is there an error in this question or solution?
