Answer 2

Did you at least draw the triangle?

Answer 3

Then you should of gotten something like this, correct?

Answer 4

radius is the hypotenuse of the right angled triangle whose base is 6 and perpendicular is 8
\[x^2+y^2=r^2\]
\[x^2+y^2=10^2\]
radius=hypotenuse =10
\[\cos \theta=\frac{ 6 }{ 10 }=0.6\]
\[\sin \theta=\frac{ 8 }{ 10 }=0.8\]

Answer 5

\[\tan \theta=\frac{ 8 }{ 6 }=\frac{ 4 }{ 3 }=1\frac{ 1 }{ 3 }\]
