Answer:
Step-by-step explanation:
We have been given that line m is parallel to line p, and
.
Since line m is parallel to line p and EJ is a transversal, so measure of angle EJG will be 39 degrees as angle EJG is alternate interior angle of angle HEF. Both angles are inside parallel lines m and p and on opposite side of transversal EJ.
We can see that angle EFG is exterior angle of triangle GFJ. Since the measure of an exterior angle of a triangle equals to the sum of the opposite interior angles.
We can see that angle IGF and angle EJG are opposite interior angles of angle EFG.
Upon substituting our given values we will get,
Therefore, measure of angle EFG is 52 degrees.
Answer:
There were 440 Standard version of songs downloaded in Web music store.
Step-by-step explanation:
Given,
Total number of songs downloaded = 1310
Total size of the downloaded songs = 4752 MB
Size of standard version of song = 2.1 MB
Size of high quality version of song = 4.4 MB
Solution,
Let the number of standard version of song be 'x'.
And also let the number of high quality version of song be 'y'.
Now, total number of songs is the sum of total number of standard version of song and total number of high quality version of song.
On framing the above sentence in equation form, we get;
Now, Total size of the downloaded songs is the sum of total number of standard version of song multiplied with size of standard version of song and total number of high quality version of song multiplied with size of high quality version of song.
On framing the above sentence in equation form, we get;
Multiplying with 10 on both side, we get;
Now multiplying equation 1 by 21, we get;
Now subtract equation 3 from equation 2, we get;
On substituting the value of y in equation 1, we get the value of x;
Hence There were 440 Standard version of songs downloaded in Web music store.
