Question

in triangle pqr , right angled at q, pr + qr =25 cm and pq =5cm . determine the values of sinp, cos p, tan p

Answer 1

HEYA,

Here is your answer

First let PR be = x .Then QR becomes 25 - x.

(As PR+QR is 25).

 Now apply pythagoras theoram 

We get (x)2  = (25 - x)2 + (5)2  on solving we get x = 13 .

so PR = 13 and QR = 12

Now sin P = P/H =12/13 cos P

= B/H = 5/13 and

tan P = P/B = 12/5 .
