A circle has a radius of \sqrt{45} 45 square root of, 45, end square root units and is centered at (-2.4,-4.8)(−2.4,−4.8)(, minus, 2, point, 4, comma, minus, 4, point, 8, ). Write the equation of this circle.

Step-by-step explanation:

The equation of a circle centre(h,k) of radius r is given by:

r²=(x-h)²+(y-k)²

If radius,

Centre, (h,k)=(-2.4,-4.8)

Substitution into the equation of the circle formula

r²=(x-h)²+(y-k)²

The equation of the circle is therefore given as:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

560
