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
