Answer 2

if angle B is going to be 45, then that means that angle C is also going to be 45 degrees, because 90+45+45=180

so A=90 B=45 C=45 also,

and when we have angles that are the same size that means that their adjacent sides are going to be equal as well, there for if CA = 12 then BA would also be 12, because there angle measure are the same

soo BA = 12
