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>

Step-by-step explanation:
Answer:
<u>x = 16</u>
Step-by-step explanation:
<em>if we want the value of x so</em>
<em></em>
<em>(4x + 1 ) = 65 (vertically opposite angles are same)</em>
<em>4x = 65 - 1</em>
<em>4x = 64</em>
<em>x= 64/4</em>
<em>x = 16</em>
