Answer:
23 degrees
Step-by-step explanation:
You are given a right angle, which is 90 degrees. Part of the right angle is 67 degrees, so you do 90-67=23
Hope this helps ^^
This is because angle B and the angle that is 67 degrees are both apart of one right angle. We can solve this through a simple equation. 90 = x +67. Subtract 67 on both sides and you get X = 23 giving you the answer 23 degrees.
