Can someone answer 6???

Choice B

15 + 5*sqrt(3)

How to get this

Let A, B, C be the sides of the triangle such that  A < B < C.

A is the short leg, B is the long leg, C is the hypotenuse

For any 30-60-90 triangle, the hypotenuse is twice as long as the short leg, so

C = 2*A

C = 2*5

C = 10

For any 30-60-90 triangle, the long leg is exactly equal to sqrt(3) times the short leg

B = A*sqrt(3)

B = 5*sqrt(3)

Now add up the three sides

A+B+C = 5+5*sqrt(3)+10

A+B+C = 15+5*sqrt(3)

d is correct
