Answer:
x = 4
Step-by-step explanation:
The exterior angles of an octagon equal 45 degrees. So if the angles are 11x+1, set it equal to 45 and solve for x.
11x+1 = 45
11x = 44
x= 4

Answer:
Brody purchased 16 songs.
Step-by-step explanation:
Ratio of the number of songs purchased by Brody(B) and Jayliah(J) = 2 : 3
------(1)
Similarly ratio of the songs purchased by Jayliah(J) and Sadie(S) = 4 : 5
-------(2)
If Sadie bought the songs (S) = 30
From equation (2),

J = 
J = 24
By substituting the value J = 24 in equation (1),

B = 
B = 16
Therefore, number of songs purchased by Brody = 16.
For 16 it's 8/10 for 17 it's 52/100 for 18 it's -92/100 for 19 it's -48/100 for 20 it's 86/100 for 21 it's 76/100
