6 one-dollars = $6 15 five-dollars = $75 9 ten-dollars = $90 Add them
all up to get $171, so that is correct. Add the number of one-dollar
bills and the number of ten-dollar bills together. 6 + 9 = 15, which is
the number of five-dollar bills, so that is correct as well. Add all the
numbers of bills together, 6 + 9 + 15 = 15 + 15 = 30.

Answer:
67.5 degrees
Step-by-step explanation:
The angles at the center of the figure = 360 degrees
Therefore, 3x + x + 90 degrees = 360 degrees
simplifying:
4x + 90 degrees = 360 degrees
4x = 360 - 90
4x = 270 degrees
x = 270÷ 4
x = 67.5 degrees
