Answer:
A. 37 degrees
Step-by-step explanation:
Since QR is tangent to the circle, it means that is in a right angle. Meaning that angle Q is equal to 90 degrees.
Since you know what two angles are equal to, you can use the triangle angle sum theorem by setting them all up to 180.
53+90+x=180
Simplify the answer
143+x=180
Subtract 143 from both sides
X=37

Answer:
52 measures
Step-by-step explanation:
Let s represent the length of the second song. Then the first song's length is 108 -s, and the difference in length is ...
(108 -s) -(s) = 4
108 -2s = 4 . . . .collect terms
54 -s = 2 . . . . divide by 2
52 = s . . . . . add s-2
Grace's second song is 52 measures long.

He did not distribute the 5 to 5 so step two had to look like 10x+25=100
