Answer:
( x + 9)² + y² = 20
Step-by-step explanation:
The standard equation of a circle is ( x – h)² + ( y - k)² = r², where the center is (h, k) and r is the radius. By plugging in the given numbers from the question, we have [ x – (-9)]² + ( y - 0)² = (2√5)².
( x + 9)² + y² = (2)(√5)(2)(√5)
(2)(2) = 4 (√5)(√5) = 5 (4)(5) = 20
( x + 9)² + y² = 20
In this right triangle, you are given the measurements for the hypotenuse, c, and one leg, b. The hypotenuse is always opposite the right angle and it is always the longest side of the triangle. To find the length of leg a, substitute the known values into the Pythagorean Theorem. Solve for a2.
