Challenge! Ready? In triangle ABC, A is a right angle, and mB = 45°. Find BC. If your answer is not an integer, leave it in simplest radical form. The diagram is not drawn to scale. http://assets.openstudy.com/updates/attachments/51468a17e4b0e8e8f6bce2a5-ilovesteven%2521%2521conexxus-1363577391515-456845224201181006am374383020.png
