There are 500 ones in 500
Answer:
????
Step-by-step explanation:
146. They are asking for the angle XY, the blue line.
For instance, imagine it is 90 deg, instead of 73, it would cut the circle in two, and XY would be 180 deg. Imagine it would be 45 degrees, it would leave a quadrant, and that's 90 deg.
So the angle * 2 (they are different angles)
I think 'TheBestBrain' thought they were asking for the supplementary angle, but I think it is the arc length angle (blue line)
2.159 • 10⁴⁵
you move the decimal point until you get a one digit decimal.
x = -9 and x = 8 when y = 0 is the answer
