Answer:
x = 67.5
Step-by-step explanation:
If a line is parallel to a side of a triangle and intersects the other 2 sides , it divides those sides proportionally.
AB is parallel to NP and intersects the other 2 sides , then
=
( substitute values )
=
, that is
=
( cross- multiply )
49.5(97.5 - x) = 22x ← distribute left side
4826.25 - 49.5x = 22x ( add 49.5x to both sides )
4826.25 = 71.5x ( divide both sides by 71.5 )
67.5 = x
