In ADEF, the measure of ZF=90°, the measure of ZD=10°, and EF = 94 feet. Find the length of DE to the nearest tenth of a foot.

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer

the answer is c. ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀
