Answer
m$\angle$A=72$^{\circ}$
Work Step by Step
as stated in question 2 that both the triangles are congurrent means two angles of both the triangles are equal.
and according to both the triangles
$\angle$A=$\angle$F
and it is given in question 3 that
m$\angle$F=72$^{\circ}$
therefore,
m$\angle$A=72$^{\circ}$
