Answer 2

Concept Introduction: Circle is a very basic concept of mathematics.

Given:

We have been Given: AOB and COD are diameters of a circle with centre O. If angle ∠OBD

$∠OBD = 40 \: degrees$

To Find:

We have to Find: then find the value of angle ∠CAO

Solution:

According to the problem, since the angle ∠OBD and ∠CAO are the alternate angles made by a transverse line. Therefore,

$∠OBD = ∠CAO = 40 \: degrees$

Final Answer: The value of angle ∠CAO is

$40 \: degrees$
