Triangle PQR has right angle Q. If sin `R=4/5`, what is the value of tan P ?

In /_\PQR , right angled at Q, PQ=105 and QR=208 , the value of tan R is:

In a triangle PQR with right angle at Q , the value of angle P is x, PQ = 7cm and QR 24 cm , then find sin x and cos x

In a triangle PQR with right angle at Q , the value of angle P is x, PQ = 7cm and QR = 24 cm , then find sin x and cos x
