Is the perpendicular bisector of . if ac = 4x and bc = 6x – 10, what is the value of x?

6x - 10 = 4x
+10 +10
6x = 4x + 10
- 4x -4x
2x = 10
x = 5
6(5) - 10 = 4×5
30-10 = 20
20=20

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
