In a right triangle ABC, C = 90°, B = 38° 35' and a = 6.434 mi. Solve for all the missing parts using the given information. (Round each answer to three decimal places for sides and to two decimal places for angle.)

You draw a triangle and label all of your given information.
so you subtract 90 from 38degree35' to get angle A.
then you use SOH CAH TOA
tan 38degree35'= b/6.434mi to solve for side b.
then use cos38degree35' = 6.434mi/c to solve for side c. 
i don't know and don't care.
