Find the measures of the angles formed by (a) two consecutive radii and (b) a radius and a side of the given regular polygon.14.

Bezzdna [24]

Answer:

Step-by-step explanation:

Let radius = r and side of a regular polygon = s

a) The consecutive radii = r + r + 1

i) For Square ( 4- sides) : r + r + 1 = 90°

2r + 1 = 90°

ii) For Pentagon (5- sides) : 2r + 1 =108°

iii) For Hexagon (6- sides): 2r + 1 = 120°

iv) For Heptagon (7- sides): 2r + 1 = 129°

v) For Octagon (8- sides): 2r + 1 = 135°

vi) For Nonagon (9- sides): 2r + 1 = 140°

vii) For 20 sides: 2r + 1 = 162°

b) A radius and a side = r + s

i) For Square (4- sides): r + s = 90°

ii ) For Pentagon (5- sides): r + s = 108°

iii) For Hexagon (6- sides): r + s = 120°

iv) For Heptagon (7- sides): r + s = 129°

v) For Octagon (8- sides): r + s = 135°

vi) For Nonagon (9- sides): r + s = 140°

vii) For 20 sides: r + s = 162°

y = r sin theta

sin theta = y/r

r sin theta = 4 Substituting for sin theta:-

r * (y/r) = 4

y = 4 is the answer

To raise money for after-school programs at an elementary school, a group of parents is holding a weekend of games in a communit

frez [133]

Answer:

$8x-40y\geq 600$ and $x>0,y>0$

Step-by-step explanation:

The number of people is $x$ and the number of hours they are present in the space is $y$ .

Per person entry cost is $8.

Per hour cost of rent is $40.

They plan to earn a minimum of $600.

Donations by all the people entering the space is $8x$

Total cost of renting the space is $40y$ which will be subtracted from the total amount of donations.

The inequality that represents the situation is $8x-40y\geq 600$ and $x>0,y>0$ .
