Answer:
C. 168°
Step-by-step explanation:
The exterior angle at any vertex of an n-gon will be ...
360°/n
So a 30-gon will have exterior angles of ...
360°/30 = 12°
The adjacent interior angle is supplementary to this, so is ...
180° -12° = 168°
_____
Using the reasonableness test
You know that the interior angles of a square are 90°, and that regular polygons with more sides have larger interior angles. The most any regular polygon's interior angle can be is 180°. The only answer choice between 90° and 180° is the correct choice: 168°.

Aliya loves music. She currently has 200 songs in her computer . The songs fall in five genres country, jazz, pop, rap, and rock. Find the percentage that is rock Country-40 Jazz- 18 Pop-52 Rap- 30 Rock-60
Answer: 30%
Step-by-step explanation:
There are 200 songs in total.
Out of these 200, there are 60 Rock songs.
The percentage of Rock is therefore:
= Rock / Total songs * 100%
= 60/200 * 100%
= 30%

Closets tale up 92 square feet of the space in rayas apartment.What is the area of Rayas entire apartment
Answer: 920 ft²
Step-by-step explanation:
Closets take up 92 ft² of Maya's apartment.
From the model presented, closets account for 10% of the entire space in Maya's apartment.
The entire area of the apartment can be represented by x.
The relevant expression is:
x * 10% = 92
x = 92/10%
x = 920 ft²

Juan bought a basketball for 40% off. If
he paid $36 for the basketball, what was
the original price?
Answer:
$24
Step-by-step explanation:
since 40% is in 100% i did 100 - 40 which i got 60
then it says that he paid $36 so I subtracted 60 - 36 and I got $24 as the answer iihope this helps! :)
100 - 40 = 60
60 - 36 = 24
The original price when he paid $36 for the basketball should be considered as the $24.
Calculation of the original price:Since
Juan bought a basketball for 40% off And, If he paid $36 for the basketball.
So it be like
= 60% of $100 - $36
= $60 - $36
= $24
Hence, The original price when he paid $36 for the basketball should be considered as the $24.

Find a coordinates of the midpoint of the line segment with the given endpoints (7,4), (9,-1)
Answer:
Coordinates of midpoint are (8,1.5).
Step-by-step explanation:
Given coordinates of end points are;
(7,4) and (9,-1)
we can find the coordinates of mid-point,
[tex](\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
Here,
x1 = 7 and y1 = 4
x2 = 9 and y2 = -1
Putting these values in formula
Coordinates of mid point = [tex](\frac{7+9}{2},\frac{4+(-1)}{2})\\[/tex]
Midpoint = [tex](\frac{16}{2},\frac{4-1}{2})[/tex]
Midpoint = [tex](\frac{16}{2},\frac{3}{2})[/tex]
Midpoint = 8 , 1.5
Hence,
Coordinates of midpoint are (8,1.5).

Find the midpoint of the line segment with the given endpoints. (5.1,5.71) and (6,3.6).
Answer:
The coordinates of the midpoint are (5.55,4.655)
Step-by-step explanation:
Midpoint
The midpoint (xm,ym) of a segment defined by points (x1,y1) and (x2,y2) is calculated as follows:
[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]
[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]
We are given the points (5.1 , 5.71) and (6 , 3.6). The coordinates of the midpoint are:
[tex]\displaystyle x_m=\frac{5.1+6}{2}=\frac{11.1}{2}=5.55[/tex]
[tex]\displaystyle y_m=\frac{5.71+3.6}{2}=\frac{ 9.31}{2}=4.655[/tex]
The coordinates of the midpoint are (5.55,4.655)
