take 2 common and cancel from numerator and denominator,
then it'll remain (1+sin) (1-sin)/(1+cos) (1-cos)
=(1-sin²)/(1-cos²)
= (cos²)/(sin²)= cot²
here cot = 15/8
so, cot²= 225/64
(sorry i can't put theta symbol anywhere, please tolerate with me and ask back if you have any doubt.)
Hope this helps :)
