If two tangents are inclined at 60˚ are drawn to a circle of radius 3cm thenfind length of each tangent |
|
Answer» Let PA and PB be the two tangents to a CIRCLE with centre O and radius 3 ∴∠APO=∠BPO = 2 1 ×∠APB = 2 1 ×60 0
=30 0
Also, OA⊥AP and OB⊥BP In a RIGHT ANGLED triangle OAP, tan30 0 = PA 3
⇒ 3
1 = PA 3
⇒PA=3 3 cm ⇒PA=PB=3 3 cm Step-by-step explanation: Please MARK mea s a brainlist |
