Answer:

11). x = 25.8°

12). x = 67.3°

Step-by-step explanation:

11). By using sine rule in the given triangle,

cos(x) = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

cos(x) = $\frac{27}{30}$

x = $\text{cos}^{-1}(\frac{9}{10} )$

x = 25.84

x ≈ 25.8°

12). By applying tangent rule in the given triangle,

tan(x) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(x) = $\frac{43}{18}$

x = $\text{tan}^{-1}(\frac{43}{18} )$

x = 67.29°

x ≈ 67.3°

Which set of polar coordinates describes the same location as the rectangular coordinates (-3,3)

Readme [11.4K]

To convert from rectangular coordinates (x,y) to polar coordinates (r, θ), the following equations should be used:

r = sqrt( x^2 + y^2)
θ = tan^-1 (y/x)

Substituting (-3,3) accordingly to the equations, we obtain r equal to 3*sqrt(2) and θ equal to -π/4. Thus, the polar coordinates equivalent to (-3,3) is (3*sqrt(2), -π/4).
