Not enough information, need some angles.
it has a triangle on the side of the question that's longest end is 40 the base is 25 and the other side i have to solve for.
You have only two bits of information.
Unless the triangle is right-angled, that is not enough.

Do you have a right-angled triangle?
Are you finding the hypotenuse?
IF so, then

h^2 = 40^2+25^2
h^2 = 2225
h = √2225 = appr 47.17 km
it is a right angle
ok, then
all done.
