Best ResponseYou've already chosen the best response.0Never mind I'll just explain the drawing. It's a graph that was a terminal point at (4, square root of 33) so it's in quadrant 3..

Best ResponseYou've already chosen the best response.0I just have to find the value of cos theta with the given terminal point...

Best ResponseYou've already chosen the best response.1@unicwaan find the hyp of that right triangle dw:1434746333384:dw once you find the hyp then you find cos(theta) since that is adj/hyp

Best ResponseYou've already chosen the best response.0So would it be the square root of 33 over 4?

Best ResponseYou've already chosen the best response.1and the adj isn't sqrt(33) also sqrt(33) isn't the same as sqrt(33)

Best ResponseYou've already chosen the best response.0No. Use a² + b² = c² to find the hypotenuse. then use the cosine formula dw:1434746621568:dw

Best ResponseYou've already chosen the best response.1dw:1434746664322:dw the hyp is always opposite side the 90 angle

Best ResponseYou've already chosen the best response.0Okay I see where I messed up, so the hyp is 7, the sides lengths are 4 and (\sqrt{33}\)

Best ResponseYou've already chosen the best response.0yes the hypotenuse is 7

Best ResponseYou've already chosen the best response.0So how would I tell which one is the adj?

Best ResponseYou've already chosen the best response.1it is the side touching the angle in the picture that isn't the hyp

Best ResponseYou've already chosen the best response.0Okay and the angle being created is closest to the origin?

Best ResponseYou've already chosen the best response.0OH! So the cos theta would be 4/7?
