When x is 4 the diagonal line is on the first line above the 4 so that would be y=1
Answer:
y(3y - 4)
Step-by-step explanation:
Both have y.
Factor y out of
Answer:
x = 30
Step-by-step explanation:
30 + 2x = 90
2x = 60
x = 30
Because both triangles appear to be isosceles!!!!!!???!!!!
A polar coordinate is that which can be written as (r, θ) where r is the radius and θ is the angle.
The radius, r, is also the hypotenuse of the right triangle that can be formed. Hence, it can be calculated through the equation,
r² = x² + y²
If we are to simplify this for the r alone, we have,
r = sqrt (x² + y²)
Substituting the known values,
r = sqrt ((4)² + (-4)²) = 4√2
The x and y can be related through the trigonometric function, tangent.
tan θ = y/x
To solve for θ
θ = tan⁻¹(y/x) = tan⁻¹(-4/4) = -45° = 315°
Hence, the polar coordinate is <em>(4√2, 315°)</em>
