Answer:
35
Step-by-step explanation:
All triangles = 180 degrees so as shown there is a right angle(90 degrees) and a 55 degree angle and there is A.
So you will subtract 90 and 55 from 180 to find A.
=35 degrees
Now or B , A and B are vertical angles which means they are congruent or equal to each other so the measure of angle B is 35.
