Answer: Choice B) 20*sqrt(2)  ft

-----------------------------------------------------

I'm assuming that the A stands for area. If so, then A = 200 is given to us
Plug this into the formula to get....
d = sqrt(4*A)
d = sqrt(4*200) 
d = sqrt(800)
d = sqrt(400*2)
d = sqrt(400)*sqrt(2)
d = 20*sqrt(2)

Please help me with this
KIM [24]

Answer:

0.40

Step-by-step explanation:

Sin(T) is Opposite over Hypotenuse, which is RS/ST.

ST = sqrt(43) so we can plug that in.

To find RS, use the Pythagorean theorem, so, 6^2+ (RS)^2= 43.

36 + (RS)^2 = 43

RS^2 = 7

RS = sqrt(7)

Thus, Sin(T) = sqrt(7/43) or 0.40
