WebSolution Let us draw the circle with extend point P and two tangents PQ and PR. We know that the radius is perpendicular to the tangent at the point of contact. ∴ ∠OQP = 90∘ We also know that the tangent drawn to a circle from an external point are equally inclined to the joining the centre to that point. ∴ ∠QP O= 60∘ Now, in ∆QPO: WebFind the length of the tangent in the circle shown below. Solution The above diagram has one tangent and one secant. Given us the following lengths: PQ = 10 cm and QR = 18 cm, Therefore, PR = PQ + QR = (10 + 18) cm = 28 cm. ⇒ SR2 = PR * RQ ⇒ SR2 = 28 * 18 ⇒ SR2 = 504 cm ⇒ √ SR2 = √504 ⇒ SR = 22.4 cm So, the length of the tangent is 22.4 cm. baju zirah kulit sapiWeb7 Through a point T ,a tangent TA and a secant TPQ are drawn to a circle AQP.
