Answer:
12/13
Step-by-step explanation:
First, use the pythagorean theorem to find EF
5^2 + EF^2 = 13^2
You get: EF = 12
Sin is opposite over hypotenuse. 12 represents the opposite and 13 represents the hypotenuse.

Answer:B
4x2 =121
4x2-121=0
using the general formula
[-b( +/-) √b2-4ac]/2a
a=4, b= 0, c=-121
x= [0 ( +/-)√02-(4*4*-121)]/2.4
= ( +/-)√1936)/8 = ( +/-)5.5
x =5.5
x = -5.5
i think it would be number 3.
Hope this helps.
