Answer:
A = 37 degrees ; B = 82 degrees
Step-by-step explanation:
the angle A plus 143 must measure 180 degrees
angle A = 180 - 143 = 37 degrees
the sum of the inner angles of a triangle is 180 degrees
A + B + C = 180
37 + B + 61 = 180
B = 180 - 98 = 82 degrees

Option B
We can store a total of 360 songs in 60 megabytes of space.
<u>Solution:</u>
It is given to us that It takes 24 megabytes to store 144 songs on a music player. We have been asked to find out what is the greatest number of songs that 60 megabytes could store.
To solve this question we can use the unitary method.
We will first find out how many songs can be stored in 1 megabyte. This can be done as follows:

Therefore, we can store 6 songs in 1 megabyte.
So, in 60 megabyte we can store the following number of songs:

So, we can store a total of 360 songs in 60 megabytes.

Answer:
27 =x
Step-by-step explanation:
The two angles are vertical angles and vertical angles are equal
4x+7 = 5(x-4)
Distribute
4x+7 = 5x-20
Subtract 4x from each side
4x+7-4x = 5x-4x-20
7 = x-20
Add 20 to each side
7+20 = x-20+20
27 =x
