Math, microeconomics or criminal justice
tan0 = 3/11, just the inverse of cotangent
for the 1st quadrant, tangent is opposite side over adjacent of a a right triangle
the hypotenuse is the square root of the sum of squares of 3 and 11 or sqr130
3 squared = 9, 11 squared = 121. 9 + 121 = 130. square root of 130 is about 11.4
sin0 = 3/sqr130 = 3sqr130/130 if you rationalize the denominator
cos0 = 11/sqr130 = 11sqr130/130, if you want to rationalize the denominator
sec0 = 1/cos0 = sqr130/11
csc0 = 1/sin0 = sqr130/3
since the cotangent is also positive in the 3rd quadrant, that would change the signs of all but the tangent, for an angle in Quadrant III

nevermind, your answer was correct! thank you so much :)10/30/20
Sophia Q.
Thank you so much! To make sure i understand the answer is, hypotenuse is 11.4 tan0= 3/11 sin0= 3 square root 130/130 cos0= 11 square root 130/130 sec0 = sqr root 130/11 csc0 + sqr root 130/3 and is this is rationalized fraction form?10/30/20
