The radius of the circle whose equation is (x-3)^2 + (y+1)^2 = 16 is
Firdavs [7]

Answer:

4

Step-by-step explanation:

The general equation of a circle with center (a, b) and radius r is given by the equation;

(x-a)^{2}+(y-b)^{2}=r^{2}

The constant in the right hand side of the equation is simply the square of the radius;

We have been given the following equation;

(x-3)^2 + (y+1)^2 = 16

Comparing this with the general equation above;

r^{2}=16\\\\r=\sqrt{16}=4

Answer:

WX = 7.9

Step-by-step explanation:

By applying tangent rule (law of tan) in the given right triangle WXY.

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

tan(27)° = \frac{\text{XY}}{\text{WX}}

0.509525 = \frac{4}{\text{WX}}

WX = \frac{4}{0.509525}

WX = 7.85

WX ≈ 7.9

Therefore, length of side WX is 7.9 units.
