Question

.

Answer 1

Are you familiar with the law of sines and the SSA case?

Answer 2

it might help to draw the pic

Answer 3

what angle can we find out using the law of sines?

Answer 4

30*sin(54)/20 is not equal to -0.83818

I'm not sure how you're getting that

Answer 5

maybe

Answer 6

I'm getting 30*sin(54)/20 = 1.21352549156242

Answer 7

the arcsine of that is undefined since sine only goes from -1 to 1

Answer 8

weird

Answer 9

yeah because we get 1.21352549156242 which leads to arcsin(1.21352549156242) = undefined, this means no triangle is possible

Answer 10

you're welcome and I'd try to find out why that glitch happened or just use another calc entirely

Answer 11

i see, that explains a lot
