Question

In traingle opq, rigth angled ar p,op=7 and op-pq=1cm the find value of sin​

Answer 1

Step-by-step explanation:

OPQ is rt angled at P .

OP=7cm

OQ-PQ=1cm

so, OQ = 1 + PQ

BY PYTHAGORUS THEOREM,

OQ^2=OP^2+PQ^2

(1+PQ)^2= 7^2 + PQ^2

1 + PQ^2+2PQ= 49 + PQ^2

2PQ= 48

PQ=24cm

OQ= 25cm
