Hi. So I just created a question for myself regarding the sine rule for non-right angled triangles and something odd came up. I just needed to do one last thing to get the answer and when I did it, it ended up being 'undefined'. Here is the working out:
Angle C=62 [degrees]
Side c= 7cm
Side b = 8cm
Find angle B:
sin(A)/a=sin(B)/b=sin(C)/c
sin(62)/7=sin(B)/8
(sin(62)/7)*8=sin(B)
sin^-1((sin(62)/7)*8)=B
And when I do that step it says undefined. I tried doing sin(62)/7 first, then doing that *8, then putting all that within the brackets of sin^-1()
Nothing has worked so far... Please help!!!
