The graph of the equation below is a circle. what is the length of the radius of the circle?
(x-6)^2+(y+5)^2=15^2
a. 15
b. 30
c. 7.5
d. 225

A) length of the radius of the circle = 15.

Step-by-step explanation:

Given  : (x-6)²+(y+5)²=15².

To Find  : what is the length of the radius of the circle.

Solution : We have given that (x-6)²+(y+5)²=15².

Standard form of circle (x-h)²+(y- k)²=r².

Where, ( h,k) are vertex point and r = radius .

On comparing (x-6)²+(y+5)²=15² with standard form of circle.

( 6 ,-5 ) are vertex and radius = 15

Therefore,  A) length of the radius of the circle = 15.

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
