Why am i so thicc in my pfp

Find the solutions for a triangle with a =16, c =12, and b = 63º

The trigonometric ratios sine and secant are reciprocals of each other

If the altitude is drawn to the hypotenuse of a right triangle, then the two triangles formed are similar to the original triangle and to each other. which set of triangles shows the similar triangles created by the altitude in the diagram?
