make a triangle

kkbrookly · Answer

I have -0.63 radians for sin theta and 1.28 for sec theta

|dw:1424211742087:dw|

anonymous · Answer

there is a picture of an angle whose tangent is $\frac{4}{5}$
find the hypotenuse via pythagoras 
then you can find any trig ratio you like
just be careful as to what quadrant you are in

kkbrookly · Answer

Alright, thank you! Are my answers correct though?

anonymous · Answer

you are not being asked for the measure of the angle, just for the other trig ratios
they probably want them written in radical form, not as decimals

kkbrookly · Answer

Oh alright. That makes sense.

anonymous · Answer

also $\sin(\theta)$ is a number, not an angle

kkbrookly · Answer

How do I convert my decimals into radical form?

anonymous · Answer

you don't
find the hypotenuse of the triangle above, then take the trig ratios you want

Thank you!
