Question

What is the measure of ∠B?

Answer 1

For this case we have that the sum of the interior angles of any polygon is given by the following expression:

$(n-2) * 180$

In this case it is observed that we have a figure with 6 sides. So:

$n = 6$

We replace:

$(6-2) * 180 = 720$

Thus, the sum of the interior angles should be 720 degrees.

So:

$B + 133 + 102 + 117 + 90 + 170 = 720\\B = 720-133-102-117-90-170\\B = 108$

Thus, angle B is 108 degrees.
