The answer is A
explanation:
i know and did it, trust me :)
30 60 90 triangle
ratio of short leg : hypo = x : 2x
given short leg x = 4 ft
so hypo a = 2x = 2 * 4 = 8
answer
a = 8 ft
----------------------------------------------
P.S.
if you need to do by using cos sin tan then
Cos (60) = Adj/Hypo = 4/a
a = 4/cos(60) as you know cos(60) = 1/2
so
a = 4 /(1/2 = 4 * 2/1 = 8
answer: a = 8 ft
180 degrees - 46 degrees
= 34 degrees
