Best ResponseYou've already chosen the best response.0look at it like a triangle like this dw:1435611781411:dw then use either sin, cos, or tan to solve for theta. Do you know which one to use?

Best ResponseYou've already chosen the best response.0oh well I like to think of SOH CAH TOA to help me figure it out. You would use Tangent to solve for theta since 6 is Opposite and 8 is Adjacent. so in your calculator put in \[\tan \frac{ 6 }{ 8}\]

Best ResponseYou've already chosen the best response.0@mastermindkakashi I got tan(6/8) = 0.1309 I don't know if my answer is right or not, though, considering the answer choices are A) 41.1 degrees B) 28.3 degrees C) 45 degrees D) 36.8 degrees

Best ResponseYou've already chosen the best response.0hm well I got a different answer than you... what do you think it is? I think we can solve it a different way

Best ResponseYou've already chosen the best response.0okay so if you look at it by pythagorean theorem, the missing side is 10. so your triangle now looks like this dw:1435612732862:dw and you can think of it as a perfect right triangle, which has 454590 angles

Best ResponseYou've already chosen the best response.0@mastermindkakashi yeah, I actually got that by solving r = √x^2 + y^2 earlier, I just don't know how to use this info to find theta

Best ResponseYou've already chosen the best response.0I think it is 45 degrees because it forms a perfect triangle
