In triangle ABC, A is a right angle, and m b=45 degrees.
What is the length of BC? If your answer is not an integer, leave it in simplest radical form.
a. 16 ft
b. 16 sq 2 ft
c. 16 sq 3 ft
d. 32 ft
I'm really confused as to how to do this... Could someone please explain and show me how to enter the whole calculation into my calculator? I don't really know how to make the whole sin thing plug in the correct ways and where to put my numbers. Thanks!!
