Answer:
B. 90°
Step-by-step explanation:
Quadrilateral inscribed in the circle with center O is a cyclic quadrilateral. 
Opposite angles of a cyclic quadrilateral are supplementary. 
Therefore, 
(b + d) + (32° + 58°) = 180°
b + d + 90° = 180°
b + d = 180° - 90°
b + d = 90°

The sale is 33% off notebooks. This can be found by first subtracting .8 from 1.2
1.2-.8=.4    Now divide .4 by 1.2 to get your answer.

=.33
.33=33%
You can also solve this mentally because if you know your basic multiplication tables, 3*4=12 and so 

 of 12 would equal 8.
