When finding missing side measures in a right triangle.
Soh = (Sine = Opposite / Hypotenuse)
Cah = (Cosine = Adjacent / Hypotenuse)
Toa = (Tangent = Opposite / Adjacent)
There are also reciprocals for these values:
Cho (Cosecant = Hypotenuse / Opposite)
Sha (Secant = Hypotenuse / Adjacent)
Cao (Cotanget = Adjacent / Opposite)
Know that there is 2 pints in a quart and 2 cups per pint so, 20x2=40x2=80.
This is simply testing if proportions are valid.
Guess-and-check, so the answer would be 40:48, since 5 x 8 = 40 and 6 x 8 = 48, where 8 is the set "constant" number
0.4=40%
75%=3/4
0.64=16/25
30%=0.3
3/20=15%
(6,-8)(6,8)
d = sqrt ((x2 - x1)^2 + (y2 - y1)^2)
d = sqrt ((6 - 6)^2 + (8 - (-8)^2)
d = sqrt ((0^2 + 16^2)
d = sqrt 16^2
d = sqrt 256
d = 16 <==
