R = 2 / (1 + sin <span>θ)
Using the following relations:
R = sqrt (x^2 + y^2)
sin </span>θ = y/R
<span>
R = 2 / (1 + y/R)
R</span>(1 + y/R<span>) = 2
</span><span>R + y = 2
R = 2 - y
sqrt(x^2 + y^2) = 2 - y
Squaring both sides:
x^2 + y^2 = (2 - y)^2
x^2 + y^2 = 4 - 4y + y^2
x^2 + 4y - 4

Answer:The team won 15 games
Step-by-step explanation:
Given no of soccer games =50
Ratio of wins to losses =3:7
Let no of wins =
and no of losses =
Now


Dividing both sides by 10
x=5
So no of wins =3x =
=15
We found the answer as 10 parts equals 50
So 3 parts equals 15
