Question

The sides of a right angle triangle pqr are pq 7cm qr 25 cm and angle p 90 respectivethen find tanq_tanr

Answer 1

Here one side is unknown i.e side PR.
On applying Pythagoras theorem, we get
PR = √RQ²-PQ²
      = √25²-7²
      = 24 cm
Now, 
tan q = opp/ adj = PR/PQ = 24/7
tan r = PQ/PR = 7/24






Hope it helps... :)
