Question

HELP: I am having a hard time getting the right answer to these.

Given a triangle where

angle A is opposite side a

angle B is opposite side b

angle C is opposite side b

If angle A = 71 and angle B =1 and side c = 8

Find the length of side a

round your answer to 2 decimal places

Given a triangle where

angle A is opposite side a

angle B is opposite side b

angle C is opposite side b

If angle A is 14^o, the length of side b is 5, and the length of side c is 6

Find the length of side a

Round your answer to 2 decimal places

If angle θ = 86^o and the length of the adjacent side is 62

find the length of the opposite side.

Round your answer to 3 decimal places (I think it's 886.641)
