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 °
Answer: answer in pic
Step-by-step explanation:
When doing the order of operations and you are put in a situation where you do two different operations, solve the problem from left to right.
In this case instead of doing 6*4 first do 24/6 first.
