Solution with steps :

Given :

△AFB≅△DEC

Since triangle AFB is congruent to triangle DEC their corresponding parts will be equal.

Which means :

m∠AFB = 37°m∠ABF = 90°

Sum of all angles of a triangle = 180°

Measure of ∠CDE :

$= \tt180 - 37 + 90$

$= \tt180 - 127$

$= \tt53$

Thus, the measure of angle CDE = 53°Then, the measure of angle BAF = 53°

Therefore, m∠A = 53°

My answer :

$\hookrightarrow\boxed{\color{plum}\bold {\tt \: \bold{m∠A = 53°}}}$
