If ab=4x+9, bc=5x+2, ac=56 find the measure of ab and bc

  ab = 29, bc = 27

Step-by-step explanation:

If we assume that point b lies on line segment ac between points a and c, then the segment sum theorem tells us ...

  ab + bc = ac

  (4x +9) + (5x +2) = 56 . . . . substitute given values

  9x +11 = 56 . . . . . collect terms

  9x = 45 . . . . . . . . subtract 11

  x = 5 . . . . . . . . . . divide by 9

Then the segment lengths are ...

  ab = 4·5 +9 = 29

  bc = 5·5 +2 = 27

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
