Question

Geometry help

1)what is the measure of the segment AB
2)what is the measure of segment CD
how so?

Answer 1

Explanation:

Answer 2

AB = 18, CD = 16

Explanation:

The 3 segments make the whole line , that is

AB + BC + CD = AD , substitute values

AB + 20 + (BD - BC) = 54

AB + 20 + (36 - 20) = 54

AB + 20 + 16 = 54

AB + 36 = 54 ( subtract 36 from both sides )

AB = 18

-----------------------------------------------------

BC + CD = BD , substitute values

20 + CD = 36 ( subtract 20 from both sides )

CD = 16
