Answer: a bigger or equal to 20
Explanation:
2a/5 - 2 _> a/4 + 1
8a/20 - 40/20 _> 5a/20 + 20/20
8a - 40 _> 5a + 20
3a _> 60
a _> 20
The angle of the sector is also equal to the arc measure of the circle. This is because a sector is made up of two radii of a circle.
A circle is 360 degrees.
60 / 360 = 1/6
The sector is 1/6 of the circle.
Hope this helps!! :)
Slope is 12/6=2
y+6=2(x+4)
y=2x-2
60 miles per hour and 55 miles per hour it will be 240 miles over 4 hours because if you divide 240 by 4 it is 60 miles faster than the other which is 55 miles per hour.
