Answer:
[tex]b = 72[/tex]
Step-by-step explanation:
The variable "b" can be found by applying the "vertical angles theorem" or "opposite angles theorem".
For example, in the image provided on this answer we can see that m∠C = 62 (measure of angle C) is equal to the m∠A = 62 (measure of angle A).
The same can be said for ∠B and ∠D; both of which have the same angle measure of 118 degrees due to the vertical angles theorem.
