Sin is opposite over hypotenuse, so sin(A) = 4/5. Cos its adjacent over hypotenuse, so cos(A) = 3/5
Since we need an angle measure we have to use an inverse trig ratio, sin^-1, cos^-1, or tan^-1.
Setting up the right triangle we have the opposite and adjacent so we use tan.
tan angle = 28/32
tan^-1 (28/32) = 41 degrees
