Answer:
Not really
Step-by-step explanation:
NOT NECESSARILY would a triangle be equilateral if one of its angles is 60 degrees. To be an equilateral triangle (a triangle in which all 3 sides have the same length), all 3 angles of the triangle would have to be 60°-angles; however, the triangle could be a 30°-60°-90° right triangle in which the side opposite the 30 degree angle is one-half as long as the hypotenuse, and the length of the side opposite the 60 degree angle is √3/2 as long as the hypotenuse. Another of possibly many examples would be a triangle with angles of 60°, 40°, and 80° which has opposite sides of lengths 2, 1.4845 (rounded to 4 decimal places), and 2.2743 (rounded to 4 decimal places), respectively, the last two of which were determined by using the Law of Sines: "In any triangle ABC, having sides of length a, b, and c, the following relationships are true: a/sin A = b/sin B = c/sin C."¹
2(3+1+2) is equivalent to 12
Remember that the domain is all possible x values.
Here, the highest x value is 2 and the lowest is -4, which makes A and D incorrect.
x can also be anything between 2 and -4, so B is also incorrect.
That leaves C our answer.
Answer:
(x - 2)² + (y - 6)² = 4
Step-by-step explanation:
Equation of a circle is given by,
(x - h)² + (y - k)² = r²
Here, (h, k) is the center of the circle
r = Radius of the circle,
From the graph attached,
Center of the circle → (2, 6)
Radius of the circle = 2 units
Therefore, equation of the circle will be,
(x - 2)² + (y - 6)² = 2²
(x - 2)² + (y - 6)² = 4
