What is the length of line segment "bc"?

Hello from MrBillDoesMath!

length BC = 9

Discussion:

The base angles of the triangle equal as indicated by the single "arcs" shown. This means the triangle is isosceles and the sides oppose the base angles are equal.  That is,

8x - 15 =  3x                      =>  subtract 3x from both sides

8x - 3x -15 = 3x - 3x = 0  =>   as 8x - 3x = 5x

5x -15 = 0                          => add 15 to both sides

5x = 15                              => divide both sides by 5

x = 15/5 = +3

Length of BC =

8x -15 =

8(3) - 15 =

24 - 15 =

9

Thank you,

MrB

the answer is simply just 6n add the two together as they have an n

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
