Question

The point (3, -4) is on the terminal side of angle Θ, in standard position. What are the values of sine, cosine, and tangent of Θ?

Answer 1

3=x

-4=y

$a { }^{2} + b {}^{2} = c {}^{2}$

$3 {}^{2} + 4 {}^{2} = c {}^{2}$

$\sqrt{} 25 = \sqrt{c {}^{2} }$

$5 = c$

sin0= 4/5

cos0=3/5

tan0=4/3
