Find the missing lengths

Ok so thats a 45 45 90 triangle so

45 n
45 n
90 n root 2

hypotenuse (90) is 15 root 2

so do 15 root 2= n root 2
do solve this multiply by root 2 on both sides
so 15 root 2 times root 2= n root 2 times
root 2

so 15 times root 4=n root 4
15 times 2 (cuz sqrt of 4 is 2)=2n (cuz
sqrt of 4 is 2

so 15*2=2n
30=2n
divide by 2 on both sides
15=n

just look at my image its way easier tho
