+128474 Can't use the tangent here
We know the side adjacent to the 28° angle and we are trying to find the side opposite the right angle (the hypotenuse )
And the trig function that relates the adjacent side and the hypotenuse is the cosine
cos (angle measure ) = adjacent / hypotenuse
oos ( 28° ) = 11 / x multiply both sides by x
x cos (28°) = 11 divide both sides by cos (28°)
x = 11 / cos (28° ) = 12.46
