In the figure shown, segment $BD$ is drawn from side $CA$ to side $CE$ to form triangle $CBD$. Angle $CDB$ is a right angle and angle $CEA$ is a right angle. Triangle $CAE$ is similar to triangle $CBD$. The measure of angle $CBD$ is $55^{\circ }$, and $AE=27(BD)$. What is the measure of angle $CAE$?

A

$(27\cdot 55{)}^{\circ }$

B

$(27+55{)}^{\circ }$

C

$55^{\circ }$

D

$27^{\circ }$
