Best ResponseYou've already chosen the best response.0but there are no angles hen (10 isnt' actual an angle within the triangle)

experimentX

Best ResponseYou've already chosen the best response.1because 25 is applied 10 degree to horizontal ... and obviously, it makes 10 degree or 18010 degree with the horizontal

Best ResponseYou've already chosen the best response.0ok...but how do i apply 170 in this triangledw:1333533509958:dw

Best ResponseYou've already chosen the best response.0dw:1333533595849:dwLike I understand how it applies outside, but how do i calculate the angle within?

Best ResponseYou've already chosen the best response.0oh. the z,c, f pattern. got it.

Best ResponseYou've already chosen the best response.0what's our next step then, cos law?

Best ResponseYou've already chosen the best response.1yep ... we have all parameters required to calculate

Best ResponseYou've already chosen the best response.2\[x^{2} = 25^{2}+30^{2}2(25)(30)\cos 170\]

Best ResponseYou've already chosen the best response.0thank you! i hadnt thought of this

Best ResponseYou've already chosen the best response.0hey guys. I'm having problems figuring out the angle (again!)

NotTim

Best ResponseYou've already chosen the best response.0I manged to get 5.4 degrees (the closest yet!), while the actual answer is 4.5 degrees.

Best ResponseYou've already chosen the best response.0i did so by using sin1(30sin170/54.8)

NotTim

Best ResponseYou've already chosen the best response.0yeah, but i still got the wrong angle...

Carniel

Best ResponseYou've already chosen the best response.0How so? Have you tried Tan,Cos, and Sin?

Best ResponseYou've already chosen the best response.0the trig ratios? it only applies to right angle triangles...doesnt it?

NotTim

Best ResponseYou've already chosen the best response.0Sorry if I sound incredulous, but I really do think it applies only to right angle triangles.

Best ResponseYou've already chosen the best response.0Do you have notes? If soo check to make sure.

NotTim

Best ResponseYou've already chosen the best response.0i dont have the notes specifically on that (its buried in a box somewhere); ill check the internet.

Best ResponseYou've already chosen the best response.0but...i can't use it here...(unless i do component method, which im not allowed to)

Carniel

Best ResponseYou've already chosen the best response.0Which methods do you recall :)?

Best ResponseYou've already chosen the best response.2you need to use Law of Sines \[\frac{a}{\sin A}=\frac{b}{\sin B}=\frac{c}{\sin C}\]

NotTim

Best ResponseYou've already chosen the best response.0yeah. i used that and got 5.4 degrees.

NotTim

Best ResponseYou've already chosen the best response.0@dumbcow yeah. i used that and got 5.4 degrees.

dumbcow

Best ResponseYou've already chosen the best response.2ok the 5.4 degrees is the angle inside the triangle, they want the angle of resultant vector > 10  5.45 = 4.55
