It's a 30 60 90 right triangle
ratio of short leg : long leg : hypotenuse = a : a√3 : 2a
If hypotenuse = 8 = 2 * 4 (a = 4)
short leg = 4
so long leg x = 4√3
answer:
B. 4√3

2nd pic
It's 45 45 90 right triangle
ratio of leg : leg : hypotenuse = a : a : a√2
Given leg= 6√2
so
hypotenuse = 6√2 * √2 = 6 * 2 = 12
Answer:
C. 12
