So.. checking the picture below
we can say y = y, or just do a substitution and end up with

once you know, how long is "x", then you can simply use the cosine of 72° to get "r"
thus
PEMDSA

(3 X 4) = 12
30-18-12 = 0
I believe that the correct answer is A

√2 ≈ 1.414 and √3 ≈ 1.732
√75 = √(25x 3) = 5√3 OR 5x1.414 = 7.07
√48 = √(16x 3) = 4√3 OR 4x1.732 = 6.92
So √75 - √48 = 7.07 - 6.92 ≈ 0.15
