PQ is a chord of length 8 cm of a circle of radius 5 cm. The tangents at P and Q intersect at a point T. the length TP in cm is:
kolezko [41]
<h3><u>Given</u><u> </u><u>:</u><u>-</u></h3>
  • PQ = 8cm
  • Radius = 5cm
  • Two Tangents = P & Q.
<h3><u>Construction</u><u> </u><u>:</u><u>-</u></h3>
  • Join OT.
<h3><u>⟼</u><u> </u><u>Solution</u><u> </u><u>:</u><u>-</u></h3>

Here, ΔTPQ is isosceles and TO is the angle bisector of ∠PTO.

[∵ TP=TQ = Tangents from T upon the circle]

⠀⠀⠀⠀⠀⠀⠀⠀∴ OT⊥PQ

  • So, PR = RQ = 4cm.

⠀⠀⠀

___________________________________________

\longmapsto{}By Applying Pythagoras Theorem in ∆OPR :

OR = √OP² - PR²

OR = √5² - 4²

OR = 3cm

__________________________________________

Now,

\leadsto∠TPR + ∠RPO = 90° (∵TPO=90°)

\leadsto∠TPR + ∠PTR (∵TRP=90°)

<u>\leadsto</u><u>∴ ∠RPO = ∠PTR</u>

⠀⠀

<u>∴ Right triangle TRP is similar to the right </u><u>triangle</u><u> </u><u>PR</u><u>O</u><u>.</u> [By A-A Rule of similar triangles]

⟼\frac{TP}{PO}  =  \frac{RP}{RO}

⟼\frac{TP}{5}  =  \frac{4}{3}

⟼TP=  \frac{20}{3}

<h3>Hence you got your answer here. </h3>

Ilya [14]

For this case we have the following fractions:

\frac {1} {3} = 0.3333\\\frac {5} {6} = 0.8333\\\frac {3} {5} = 0.6

So we have to:

0.3333

This is equivalent to:

\frac {1} {3}

Answer:

\frac {1} {3}

The answer is Option A
