Jisko aata hai vohi kre wrong ans mt karna.
If the angle between two tangents drawn from an external point P to a circle radius a and centre O,is 60°,then find the length OP.
mujhe malum nahi yaha pe answer kaise likhte hai isliye details me daaldiya
OA=a
OP=?
ANGLE BETWEEN TANGENTS=60°
Tangents are equally aligned to each other
=>
IN ∆OPA,
=60°
Cos 60°=OA/OP
1/2 =a/OP
=> OP = 2a(Ans)
