Question

In the given figure,
BAO = 40° and BCO = 56. Calculate the measure of AOC.​

Answer 1

${\huge\mathfrak\color{Red}{Answer~is~ 176° }}$

Explanation :-

angle ABC = 90°

{ angle in semicircle is always = 90° }

angle BAO = 40° { Given }

angle BCO = 56° { Given }

Now in ABOC,

angle ABC + BAO + BCO + AOC = 360°

90° + 56° + 40° + angle AOC = 360°

angle AOC = 360 - 186

$\boxed{\tt{ angle~AOC = 176° }}</p><p>$

Answer 2

Step-by-step explanation:

AOC is not a straight line there for Arc ACB cannot be called a semicircle
