Answer:
Betina is [tex]1\ m\ 55\ cm[/tex] tall
Step-by-step explanation:
let
x ----> Brian's height
y ----> Bonnie's height
z ----> Betina's height
we know that
[tex]1\ m =100\ cm[/tex]
[tex]1\ m\ 87\ cm=100\ cm+87\ cm=187\ cm[/tex]
so
[tex]x=187\ cm[/tex]
[tex]y=x-58[/tex]
substitute the value of x
[tex]y=187-58=129\ cm[/tex]
[tex]z=y+26[/tex]
substitute the value of y
[tex]z=129+26=155\ cm[/tex]
[tex]155\ cm=100\ cm+55\ cm=1\ m\ 55\ cm[/tex]
therefore
Betina is [tex]1\ m\ 55\ cm[/tex] tall
