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

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
