Best ResponseYou've already chosen the best response.1we know opposite and adjacent. which are opposite=50 and adjacent=75

Best ResponseYou've already chosen the best response.2oh I see, I was thinking they just wanted theta, nvm

jim_thompson5910

Best ResponseYou've already chosen the best response.2ok so you'll need the hypotenuse first because sin(theta) = opp/hyp

Best ResponseYou've already chosen the best response.2so use the pythagorean theorem to find x dw:1441845085421:dw a^2 + b^2 = c^2 50^2 + 75^2 = x^2 x = ???
