Answer:
Choice A.......< B is 147 degrees
Step-by-step explanation:
The total sum of the interior angles of a pentagon is 540 degrees
...So let's count the angles that we already have:
<A is 90
<B is ?
<C is 105
<D is 108
<E is 90
Noticed that both angles A and E are 90 since they have that little square that represents a straight angle.
Let's find the value for <B
90+ x + 105 + 108 + 90= 540
393 + x= 540
x= 540 -393
x = 147
So angle B is 147 degrees
