Find tan A.

For the given triangle, the tan of angle A equals C. .

Step-by-step explanation:

Step 1; In the given triangle, the opposite side has a length of 15 units, the adjacent side has a length of 36 units while the hypotenuse of the triangle measures 39 units. To calculate the tan of angle A we divide the opposite side's length by the adjacent side's length.

cos A = .

Step 2; The opposite side's length = 15 units,

The adjacent side's length = 36 units.

cos A = , dividing the numerator and the denominator by 3, we get

cos A = , which is option C.
