cos(t) = 9/20 t = arccos(9/20)
I'm sorry I'm really bad at this but what is arccos?
its the inverse function to cosine
it undoes a cosine
\[t= cos^{-1}(9/20)\] might be a more familiar notation for you

Yes it is thank you
yw
i got no idea of the actual value without a calculator tho
google arccos(9/20) if need be and itll pop out a radian value for you
So it's 63.26 degrees I think. Thank you so much
