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>

Answer:
triangles AQB and AVB are congruent.
ΔLKJ ≅ ΔLMJ
Step-by-step explanation:
We have to prove that triangles LKJ and LMJ are congruent so let's
Consider triangles LKJ and LMJ;
∠KLJ=∠MLJ {Given that LJ bisects ∠KLM}
∠KJL=∠MJL {Given that LJ bisects ∠MJK}
LJ=LJ {common side}
So using ASA, triangles AQB and AVB are congruent.
Hence it is proved that
ΔLKJ ≅ ΔLMJ

Step-by-step explanation:
An initial random selection of mail-order physicians representing firm A worked an average of 50.1 hours per week. My goal is to reject the Null Hypothesis since it is employed to make no difference. In this case,
Medical insurance changes are attributed to reducing the average workweek. New medical coverage is claimed to be have reduced your average workday after the government change.
