The point (−3, 1) is on the terminal side of angle θ, in standard position. what are the values of sine, cosine, and tangent of θ? make sure to show all work.

sq rt(-3^2+1^2)

sq rt(9+1)

sq rt(10) would be the length of the radius in this case.

then we use the sine cosine and tangent fractions

sin: y/r

cos: x/r

tan: y/x

with the values plugged in the equations are

sin: 1/sqrt(10) since there can´t be a sq rt in hte denominator we change it to 1(sq rt(10))/10

cos: -3/sqrt(10) since there can´t be a sq rt in the denominator we change it to -3(sq rt(10))/10

tan: 1/-3 this one can stay the same.

this would be the measures of sin, cos, and tan.

i would say c is the best answer, hope it's right!

good luck! =)

cutie~

the answer is 0.071

good luck! : d
