Question

In the given figure, O is the centre of the circle. If OD LAC, OB = 5 cm, OD=3 cm, then length of BD is:​

Answer 1

Answer:

since,we know that OD is perpendicular to AC.

therefore, In right triangle ODB,

(BD) ²=(OD)²+(OB) ²

BD²=(3) ²+(5) ²

BD²=9+25

BD²=34cm

BD=√34

BD=2√17cm

therefore, Required value of BD is 2√17 cm.
