Answer:
BC = 153 m
Explanation:
three or more parallel lines are intersected by 2 or more transversals , the parallel lines divide the transversals proportionally.
to calculate the distance AC we require BC , then
=
( substitute values )
=
( cross- multiply )
80 BC = 72 × 90 = 6480 ( divide both sides by 80 )
BC = 81
Then
AC = AB + BC = 72 + 81 = 153 m
