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

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
