Sin 30= x/8
X= sin 30*8
X=4
To convert from rectangular coordinates (x,y) to polar coordinates (r, θ), the following equations should be used:
r = sqrt( x^2 + y^2)
<span>θ = tan^-1 (y/x)
</span>
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).
Sure, each of the following lines.
8x-6+3x-1
11x-6-1
and, 11x-7
12/x+5
x represents “a number” because it’s unknown and the + sign is because the words sum
