12. CM if the pentagon's area is 125 ft? and VW = 8.5 ft
13. Sam wanted to find m_ VWX, so he divided 360° by 5 and got 72°. But when he looked at the angle, he
realized it must be greater than 90°.
a. Explain Sam's error.
b. Find m2 VWX.
c. Make a conjecture relating the measures of an interior angle in a regular polygon and a central angle.

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

8 < i think

hope this !
