I don't have the diagram — can you confirm the triangle and which sides are 10 and 25, and whether there's a right angle (and where)?

If the intended picture is triangle RST with a right angle at S, RT the hypotenuse = 25 and RS = 10 (so RS is the side adjacent to angle T), then

cos(∠T) = adjacent/hypotenuse = RS/RT = 10/25 = 2/5.

If your diagram is different, please upload or describe it and I’ll recompute.
