Respuesta Es -3 (tried my best I’m only in Spanish two my main language is English)
Remember that transformation between Cartesian and polar system are:
x=r*cos(α)
y=r*sin(α)
From this we can conclude that:
r=√(x^2 + y^2)
Using trigonometry transformations we can write:
r=sin(2α) = 2sin(α)cos(α)
Now we can multiply both sides with r^2:
r^3 = 2(r*sin(α))*(r*cos(α))
Now using some replacements we can write:
(x^2 + y^2)^(3/2) = 2*x*y
The missing part is the number

Answer:
1410ft²
Step-by-step explanation:
20 * 12 * 2 + [62 * (15 + 12)] =
480 + (62 * 15) =
480 + 930 =
1410ft²
