Answer:

angle b is 135 degrees

Step-by-step explanation:

a is 45 degrees, which means c is as well. a quadrilateral has 360 degrees, so you subtract the angles you already know from 360 to get 270 left, and divide that by 2 because there are 2 angles left that you dont know, b and d, and they are congruent. for angles d and b you get 135, so theres your answer, hope it helps :)

360-45-45=270

270/2=135
