Question

Find the value of sec Θ for the angle shown.
I have included a document..

Answer 1

Know what sec is in terms of x, y, and r?

Answer 2

With this, and a little understanding of trig ratios, you can answer these:

\(\sin\theta = \tfrac{y}{r}\)

\(\cos\theta = \tfrac{x}{r}\)

\(\tan\theta = \tfrac{y}{x}\)

\(r^2=x^2+y^2\)

Answer 3

I actually solved it already, but thanks :)

Answer 4

Kk. Have fun!
