I think you should try this... ?!
If you could help me in any way it would be great!!! I accidently typed the wrong question!(I sometimes wonder how I got into this maths class=])
this is the right question:
A boat travels 6.3km due north and then turns 17degrees towards the west and travels a further 7.2kms. How far is it from it's initial position?
x^2=6.3^2+7.2^2-2(6.3)(7.2)cos17
x^2=91.53-90.72Xcos17
x^2=91.53-86.76
x^2=4.77
x=2.18
any help would be great! Thank you for taking the time to help me with my trig h/w!!
Hello, xch3m_is_l0v3x!
You didn't make a sketch, did you?
A boat travels 6.3km due north .
and then turns 17° towards the west .
and travels a further 7.2kms. .
How far is it from it's initial position?Code:C * N \\ : \ \ 7.2 : \ \ : \ \17°: \ \ : \ * B \ | \ | \ | 6.3 \ | \| * A
