Question

In A OPQ right angled at P, OP= 9cm and
OQ- PQ = 1cm . Determine the values of sinQ
and cosQ​.
irrevelent and will be reported
if there is no full steps it will be also reported
I am sorry its because I am in a hurry.

Answer 1

Answer:

OQ

2

=OP

2

+PQ

2

⇒(PQ+1)

2

=OP

2

+PQ

2

[∵OQ−PQ=1⇒OQ=1+PQ]

⇒PQ

2

+2PQ+1=OP

2

+PQ

2

⇒2PQ+1=49

⇒PQ=24cm

∴OQ−PQ=1cm

⇒OQ=(PQ+1)cm=25cm

Now, sinQ=

OQ

OP

=

25

7

and, cosQ=

OQ

PQ

=

25

24
