when solving for a triangle with given a angel and adjancent side , using cos gives you way of value and sec gives you the right results why . for ex:
21.3 is the angel and 31.6 is the adjacent side
another ex 57.3 is the angel and 135 feets is the side . you try them and let me know
hence, for the first one using cosine gives the results of 29. something degrees and sec gives you the right answer that is 33.9

Multiplying the hypotenuse by the cosine of the angle will give you the adjacent leg of the triangle, but if you have the adjacent leg given and wish to find the hypotenuse, you must divide the length of the leg by the cosine of the given angle.
Dividing by the cosine is the same thing as multiplying by (1/cos of angle), and since the inverse of cosine is secant, (1/cos x) is the same thing as sec x.

Youre using two different formulas? Hence two different results.
