Answer:
[tex]B\text{\placeholder{⬚}= 67\degree}[/tex]
Explanation:
Here, we want to calculate the value of the angle at B
Mathematically, the sum of the interior angles of a triangle is 180 degrees
We have that as:
[tex]A\text{ + B + C = 180\degree}[/tex]
Thus, we have it that:
[tex]\begin{gathered} 32\text{ + B + 81 = 180} \\ B\text{ = 180-32-81} \\ B\text{ = 67\degree} \end{gathered}[/tex]
