Step-by-step explanation:

What is the measure of an interior angle in a regular hexagon?

720/6 = 120

Answer

120°

2.What is the sum of the angle measures in a 14-gon?

180 * (n - 2) in this case n = 14

so 180 * (12) = 2160

Answer

2,160°

3. In a right triangle, the measure of one acute angle is 71°. What is the measure of the other acute angle?

90 - 71 = 19

Answer

19°

4.Which quadrilaterals always have both line symmetry and rotational symmetry?

Answer

square

Step-by-step explanation:

vertex-form equation for a vertical parabola with vertex (h,k):

y = a(x-h)² + k

y = -1.5(x+2)²

vertex (-2,0)

y-intercept = -1.5(0+2)² = -6
