Find the angle of triangle inside circle

Let's say I have,

Now I have to find the angle CBA. Given that we know just 26 given above.

• Think about the measure of $ACB$ – user261263 Dec 3 '16 at 11:06

Hint: $\angle ACB$ is 90 degrees because AB is the diameter of the circle.
$\angle CAB=26$ and $AB$ is a diameter hence $\angle ACB=90$.
So $\angle CBA=180-(90+26)=64$.
