2a is the length of OP
u need to use tangent is perpendicular to radius
prove congruency and then use trig
u get tan 60 is root 3
multiply this with a u get length of tangent from p to circle
then use pythagoras theorem
u get OP =2a

Step-by-step explanation:

OA=a

OP=?

ANGLE BETWEEN TANGENTS=60°

Tangents are equally aligned to each other

=> <OPA=<OPB=30°

IN ∆OPA,

<POA=180°-90°-30°

=60°

Cos 60°=OA/OP

1/2 =a/OP

=> OP = 2a

Heya user..!!

Here is ur answer.!!

__________________________________________________________________

Given :

Angle APB = 60°And Angle OPA = 30°To find the length OP = ?In triangle OPA :

Sin 30° = opposite/ hypotenuse = a/PO

1/2 = a/PO

∴ PO / OP = 2a.

So, the length of OP = 2a.
