A triangle is shown with an angle labeled as 45 degrees and its adjacent side as 3 rad . Find the missing sides

Question

the opposite side is labelled as y and the hypotenuse is labelled as x

Answer 1

adjacent side = 3

hypotenuse = x, y= opposite side

tan45 = opposite over adjacent side = y/3 = 1, y= 3

hypotenuse = 3sqr2 = x = about 3(1.414) = 4.242 = x

(normally x is the adjacent side and hypotenuse = sqr(x^2+y^2))
