PQ is a chord of length 8cm of a circle of radius 5cm. The tangent at P and Q intersect at a point T. Find the length TP?
CAN I GET THE CORRECT EXPLATION OF THIS EXAMPLE????
We have a circle of radius 5 cm with a chord of length 8 cm.
We have to find length TP.
PM=4 cm .......(perpendicular from the centre divides the chord)
OM=3 cm .......(by using Pythagorean triplet)
Let and TP be x.
Use trigonometric ratio in the triangle PMO and POT we get,
Therefore, TP=6.66 cm
