    What is the sum of the measures, in degrees, of the interior angles of a 16-sided polygon?

    • A. 

      360°

    • B. 

      2520°

    • C. 

      2880°

    • D. 

      22.5°

    Correct Answer
    B. 2520°
    Explanation
    A polygon with n sides has n-2 interior angles. Therefore, a 16-sided polygon has 16-2=14 interior angles. The sum of the measures of the interior angles of a polygon can be found using the formula (n-2) * 180°. Plugging in n=16, we get (16-2) * 180° = 14 * 180° = 2520°.

    What is the measure of each exterior angle in a regular nonagon?

    • A. 

      40°

    • B. 

      360°

    • C. 

    • D. 

      1260°

    Correct Answer
    A. 40°
    Explanation
    The measure of each exterior angle in a regular nonagon is 40°. In a regular polygon, all exterior angles are congruent, meaning they have the same measure. Since a nonagon has 9 sides, the sum of all exterior angles is 360°. To find the measure of each exterior angle, we divide the sum by the number of sides, which gives us 40°.

    • D. 

      126°

    Correct Answer
    D. 126°
    Explanation
    In a parallelogram, opposite angles are congruent. Since angle 1 is opposite to angle 3, which measures 54°, angle 1 must also measure 54°. Additionally, the sum of the measures of the interior angles of a parallelogram is always 360°. Since angle 3 measures 54°, the sum of angle 1 and angle 3 is 180°. Therefore, angle 1 must measure 126°.

    • D. 

      1.73

    Correct Answer
    A. 5.39
    Explanation
    The distance between two points in a coordinate plane can be found using the distance formula, which is the square root of the sum of the squares of the differences in the x-coordinates and y-coordinates. In this case, the x-coordinate difference is 5-0 = 5, and the y-coordinate difference is -2-0 = -2. Squaring these differences gives 25 and 4, respectively. Adding these squares gives 29. Taking the square root of 29 gives approximately 5.39, which is the distance between the origin and the point (5, -2).

      (7, 0)

    • C. 

      (3, 0)

    • D. 

      (0, -21)

    Correct Answer
    B. (7, 0)
    Explanation
    The x-intercept of a line is the point where the line intersects the x-axis. To find the x-intercept, we set y=0 in the equation y=3x-21 and solve for x. When y=0, we have 0=3x-21. Adding 21 to both sides, we get 21=3x. Dividing both sides by 3, we find x=7. Therefore, the x-intercept of the line is (7, 0).

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

    • B. 

      (x+3)^2 + (y-1)^2 = 4

    • C. 

      (x-3)^2 + (y+1)^2 = 4

    • D. 

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

    Correct Answer
    C. (x-3)^2 + (y+1)^2 = 4
    Explanation
    The equation of the circle graphed below is (x-3)^2 + (y+1)^2 = 4. This is because the equation of a circle with center (h, k) and radius r is (x-h)^2 + (y-k)^2 = r^2. In this case, the center of the circle is (3, -1) and the radius is 2 (since 2^2 = 4). Therefore, the correct equation is (x-3)^2 + (y+1)^2 = 4.

      X^2 + y^2 = 9

    • B. 

      X^2 + y^2 = 3

    • C. 

      (x+3)^2 + (y-3)^2 = 9

    • D. 

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

    Correct Answer
    A. X^2 + y^2 = 9
    Explanation
    The equation of a circle is given by (x-a)^2 + (y-b)^2 = r^2, where (a,b) is the center of the circle and r is the radius. In this case, the equation x^2 + y^2 = 9 represents a circle with center at the origin (0,0) and radius 3. Therefore, it is the correct equation for the circle graphed below.
