because the opposite is not defined you cant use sine, but you have adjacent and the hypotnuse which means you can use cosine

nop its base/hyp

Valkarie70 Group TitleBest ResponseYou've already chosen the best response.0
but you dont have the base therefore you must use cosine

so it should be 2.28/4.07

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

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

Valkarie70 Group TitleBest ResponseYou've already chosen the best response.0
yes, so you cant do sine because it requires you use adjacent

Some 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

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

base and hypotaneous will be the sides with angle.. and perpendicular is the side opposite of the angle on which we are working.

dw:1352832995681:dw if we are working on this mark angle then your Hyp base and perp will be this.

hahah lol i am not crazy :P and yes thats an easy way to remember sides we have to take with cos sin and tan..

Not yet... 0.560 that is the cosine of Angle A. Now you need to use "Inverse Cosine" to get angle A.

do 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: \[\cos ^{1}\]

cosine = a/c

Yes, that's exactly right :) Nice work.

If 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.
