Question

In each of the following figures ,O is the centre of the circle .find the value of x and y​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

$\huge{ \red{x = 34 \: cm }} \\ \\ { \huge \red{ y = 16 \: cm}}$

Step-by-step explanation:

Since length of tangents from same external point of circle are equal , so

AB = BC = y = 16 cm

Now use Pythagoras theorem in ∆OAB

${x}^{2} = {30}^{2} + {16}^{2} \\ \\ {x}^{2} = 900 + 256 = 1156 \\ \\ x = \sqrt{1156} = 34 \: cm$
