Question 802598
Let theta be an angle in standard position. If the point (-7,-24) is on the terminal side of theta, find the sin of theta and tan of theta. Express the answers in fraction form with simplified radical form. 
***
use x for theta
reference angle x is in quadrant III where sin<0, cos<0, tan>0.
hypotenuse of reference right triangle=&#8730;(7^2+24^2)=&#8730;(49+576)=&#8730;625=25
cosx=adjacent side/hypotenuse=-7/25
sinx=opposite side/hypotenuse-24/25
tanx=sinx/cosx=-24/-7=24/7
