Well you have to find out how many cd is 40% and 30%
30% = 30x.3=9
40% = 30x.4=16
now add 16 and 9
16+9=25 now subtract 25 from 30 and see that you have 5 cd of a different type of music to find that as a % divide 5 by 35 to get .14 I rounded it to the nearest hundreth now move the decimal over 2 spots to get 14%
Step-by-step explanation:
Given: 
As the domain for the inverse sine function is 1 ≤ x ≤ 1 as this is the range for the sine function.
The range for the function is the same as the range for the cosine function, 1 ≤ y ≤ 1
As
So, using the identity 
As the sin and inverse sin function do cancel each other, so only x² is left.
Hence,

5)
x = 132 - 42
x = 90
Answer
90 degrees, right angle
6)
180 - 126 = 54
The other two are congruent so 54/2 = 27
Answer
27
7)
An exterior angle of a triangle is equal to the sum of the opposite interior angles
So
6x = 38 + 82
6x = 120
x = 20
Answer
20
8)
Sum of interior in a triangle = 180 degrees
So
2x - 3 + 23 + 128 = 180
2x + 148 = 180
2x = 32
x = 16
Answer
16
