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.)

ALISON,
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.
