If the perimeter of isosceles δabc is 45 and side ac is 11, give one possible value for the length of side bc.

Hello from MrBillDoesMath!

Discussion:

In ΔABC side AC is 11, but as the triangle is isosceles the other leg also has length 11. Let the third, unknown side, be called x. Then

11 + 11 + x = Perimeter = 45.

11 + 11 + x = 45                 => as 11 + 11 = 22

22 + x = 45                      => subtract 22 from both sides

x = 45 -22 =  23

Thank you,

MrB

answer: yes, he is correct

step-by-step explanation: 10x-1=59

                                              1-1=0     59+1=60

60/10=x=6

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
