Answer 2

\[t=\frac{ \arccos (\frac{ 3 }{ 7 }) }{ 2 }\]

Answer 3

That's it? How did you get it? @alivejeremy thanks you btw!

Answer 4

You're Welcome! Want me to add steps? :)

Answer 5

Yes that would be fabulous!

Answer 6

Ok! :D

Answer 7

Divide both sides by 7
\[\cos2t=\frac{ 3 }{ 7 }\]
Than Invert function on both sides
\[2t=\arccos (\frac{ 3 }{ 7})\]
Therefore,Divide both sides by 2
\[t= \frac{ \arccos (\frac{ 3 }{ 7 })}{ 2}\]

Answer 8

:D
