Question

A tangent PQ at a point p of a circle of radius 5 cm meets a line through the centre O at a point Q so that OQ=12cm.length PQ is :. (A)12cm. (B)13cm. (C)8.5cm. (D)√119cm

Answer 1

Answer:

12 cm

Step-by-step explanation:

• OQ=12 cm
• POQ=180degree

• PO +OQ=180
• PO+12=180

• PO=180-12
• PO=168 degree

• PQ=PO+OQ
• PQ=168+12

• PQ=180 cm
