Question

find the length of x and y​

Answer 1

Answer:

0.8125

Step-by-step explanation:

13 l 16

= 0.8125

Answer 2

Answer:

Here, OA=30cm, AB=16cm and OB=X

By using pythagorus theoram,

OB^2=OA^2+AB^2

So,

$ob = \sqrt{}oa {}^{2} + ab {}^{2} \\ = \sqrt{}30 {}^{2} + 16 {}^{2} \\ = \sqrt{}900 +256 = \sqrt{}1156 = \\ = 34$

Therefore length of X=34cm.

Let BC=Y

BC=16cm(AB=16cm, ABand BC are tangents, and they are from the same point also.So AB=BC)

HOPE IT HELPS YOU DEAR.......
