ZD, ZE, and ZF are the perpendicular bisectors of △ABC. Use that information to find the length of each segment. Note that the figure is not drawn to scale. adbecfz Given: ZF = 40, ZA = 83, AB = 158 Find: AD and ZB The line segment AD has length . The line segment ZB has length .

  AD = 79

  ZB = 86

Step-by-step explanation:

If Z is at the intersection point of the perpendicular bisectors of the sides of the triangle, it is the "circumcenter", so is equidistant from the vertices.

  ZB = ZA = 83

If D is the midpoint of AB, then ...

  AD = AB/2 = 158/2 = 79

the answer is c. 23/3

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
