Find the length of EF in this Pythagorean theorem problem and show work please and thanks you

I'm not sure if you can solve this with Pythagorean Theorem because as far as I know, you need sides not angle+side combination. Despite this, let's solve this one using sine law, cosine law or even tangent.

Step-by-step explanation:

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3

1/3 + 1/5 = 8/15.

step-by-step explanation:
