5/8 (= 0.625)

Step-by-step explanation:

tan A = sin A / cos A

we have here a triangle that is much bigger than to fit into our snuggly around a norm circle (radius = 1).

so, we could either see it embedded in a circle with a radius of the square root of 89, or surrounding a circle with the radius of 8.

in the first case

$5 = \sin(a) \times \sqrt{89}$

$8 = \cos(b) \times \sqrt{89}$

in the second case 5 is already tan A but stretched by the radius 8.

so,

$5 = \tan(a) \times 8$

so, in both cases the answer is 5/8.
