A sector is cut from a circle of radius 21 CM the angle of the sector is 150 degree find the length of Arc and area

x=-2

step-by-step explanation:

28-32x=92

-32x=92-28

-32x=64

x=64/-32

x=-2

-x represents miles per gallon

-y represents cargo weight

-vehicle traveled an average of 5.3 miles per gallon(x1) with load of 22 tons (y1)

- vehicle traveled an average of 6.3 miles per gallon( x2) with load of 18 tons( y2)

so, equation now becomes

so, option a) is correct
