so for this you would use sin cos tan which i assume you know. for this one, you would use cos since u have the adjacent side and its asking for the hypotenuse. the equation is cos(41)=14.7/x since the x is on the bottom of the fraction, you want to swap cos(41) and x. so the final equation you want to input into your calculator is x= 14.7/cos(41). answer is 19.5
