A:
To solve this problem yo need to have the "x", the "y", and the radius. To find the radius since it is not given we use the formula. 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.
