Best ResponseYou've already chosen the best response.0because the opposite is not defined you cant use sine, but you have adjacent and the hypotnuse which means you can use cosine

Best ResponseYou've already chosen the best response.0but you dont have the base therefore you must use cosine

Best ResponseYou've already chosen the best response.0well i think thats the way it should be done.. maybe you can ask someone else to confirm it.

Best ResponseYou've already chosen the best response.0well no cos function will be use.. adjacent = 2.28 , hyp =4.07

Best ResponseYou've already chosen the best response.0yes, so you cant do sine because it requires you use adjacent

Best ResponseYou've already chosen the best response.0Some People Have Curly Brown Hair Through Proper Brushing. now just look first letter of each word. S=sin, P= perpendicular, H= Hyp, C=Cos , B= bAse, T=tan

Best ResponseYou've already chosen the best response.0that is a formula for making things easy.. mean when u use sin=perp/hyp cos= base /hyp , tan =perp/base

Best ResponseYou've already chosen the best response.0base and hypotaneous will be the sides with angle.. and perpendicular is the side opposite of the angle on which we are working.

Best ResponseYou've already chosen the best response.0hahah lol i am not crazy :P and yes thats an easy way to remember sides we have to take with cos sin and tan..

Best ResponseYou've already chosen the best response.0Not yet... 0.560 that is the cosine of Angle A. Now you need to use "Inverse Cosine" to get angle A.

Best ResponseYou've already chosen the best response.0do you have calculator? I am using the windows calculator... it has a button called "Inv" (for inverse), so I hit that button, then the "cosine" button. Actually, when I hit "Inv", then my cosine button turns to cos^1 like: \[\cos ^{1}\]

Best ResponseYou've already chosen the best response.0Yes, that's exactly right :) Nice work.

Best ResponseYou've already chosen the best response.0If you have an angle, you can use the sine, cosine, and tangent ratios to solve for a missing side. If you don't have an angle shown, but you do have side lengths shown, you can use the same ratios, but then with inverse cosine, inverse sine, or inverse tangent to solve for the missing angle.
