b $.05
Step-by-step explanation:
5 lbs is .80 and 8 lb is .75 so a 5 cent difference per lb
The answer to the question is (0,5)
Answer:
60 °
Step-by-step explanation:
Applying the law of sine we have the following:
160 / Sin B = 80 / Sin 30 °
We solve for B and we have:
160 / Sin B = 80 / 0.5
160 / Sin B = 160
Without B = 160/160
B = Arc Sin (1)
B = 90 °
Now to calculate the other angle (true
course) would be:
A = 180 ° - (B + C)
A = 180 ° - (90 ° + 30 °)
A = 60 °
That is to say that true course is 60 °
Remember that straight lines are 180°. For #1 angle 1 would be 40°, since 140°+40°=180°
