The angle of B is 56.2 degrees
<em><u>Solution:</u></em>
Given is a right angled triangle ABC
From given figure,
AB = 9
CB = 5
We have to find the angle of B
Let the angle of B be
By definition of cosine,
Here, adjacent = CB and hypotenuse = AB
Therefore,
Taking cos inverse on both sides,
Thus the angle of B is 56.22 degrees
