Answer:
Step-by-step explanation:
construct a semicircle with center at C and cutting line AB at D and E.
With D and E as centres draw two arcs with same radius cutting at P and Q.
Join P and Q. It is the required perpendicular.
Y=18.
x/y=x/y
7/9=14/y
y=14*9/7
y=18
This problem is currently unsolvable as we do not know if the semi-circle has a radius of 31 or 19.
