    right you notice the answer choices all have \(X=53^\circ\) so that was kind of a no brainer

    @misty1212 omg youre right haha well i got down to it and i'm at \[\frac{ \sin88 }{ 70 }=\frac{ \sin53 }{ x }\] i just put x for no reason

    a) we should the x for sure because there is an x there b) it is silly to put the variable in the denominator !

    \[\frac{x}{\sin(53)}=\frac{70}{\sin(88)}\]

  18. misty1212

    so \[x=\frac{70\sin(53)}{\sin(88)}\]

    law of sines and cosines not as bad as a lot of trig for sure identities are much worse and solving equations

    once you get the hang of it, you will think it is easy, trust me it is frustrating learning for sure, and i get the impression this is an on line class so it is kind of diy but don't give up plus you can always ask here seems like you are doing ok to me

    maybe you got stuck on the proofs, the mechanics of solving triangles gets routine though law of sines, law of cosines, that is all

    If two angles were given and one side I would immediately think of law of sine. When two sides are given with an angle makes sense to use law of cosine

    It's all about practice to master the concept! No need to get frustrated as learning new concepts take some time to sink in. Just keep practicing
