Answer:
107 degrees
Explanation:
The lines intersect to create a triangle. The sum of the interior angles of a triangle is 180 degrees.
a + b+ c = 180
We deduce the unlabeled angle (in the lower right corner) by considering the line that goes from that angle to the a angle on the left side. The line itself has a 180 degree angle (on each side). And we know the exterior angle is 107 degrees... that leaves 73 for the interior angle.
We take the equation above again... by putting now the value of C (the un-named angle):
a + b + 73 = 180
We isolate the a+b part... to get a+b = 107, the same value as the exterior angle.
The excerpt that is from an opera aria by Mozart is; Excerpt A
What is the given Excerpt?
Mozart was an Austrian composer, widely recognized as one of the greatest composers in the history of Western music. Unlike any other composer in musical history, he wrote in all the musical genres of his day and excelled in every one. His taste, his command of form, and his range of expression have made him seem the most universal of all composers; yet, it may also be said that his music was written to accommodate the specific tastes of particular audiences.
Mozart wrote several successful operas, such as The Marriage of Figaro (1786), Don Giovanni (1787), and The Magic Flute (1791). Mozart also composed a number of symphonies and sonatas. His last symphony—the Jupiter Symphony—is perhaps his most famous.
