Answer: The measure of angle A is 60 degree.

Explanation:

It is given that the Triangles A B E and D C E share vertex E. Angle B is 18 degrees. Angle C is 43 degrees. Angle D is 35 degrees.

According to angle sum property, the sum of angles of a triangle is always 180 degree.

In triangle CDE,

\angle ECD+\angle CDE+\angle DEC=180^{\circ}

43^{\circ}+35^{\circ}+\angle DEC=180^{\circ}

78^{\circ}+\angle DEC=180^{\circ}

\angle DEC=180^{\circ}-78^{\circ}

\angle DEC=102^{\circ}

According to opposite vertical angle property.

\angle AEB=\angle DEC

\angle AEB=102^{\circ}

Use angle sum property is triangle ABE.

\angle ABE+\angle BEA+\angle EAB=180^{\circ}

\angle ABE+102^{\circ}+18^{\circ}=180^{\circ}

\angle ABE+120^{\circ}=180^{\circ}

\angle ABE=60^{\circ}

Therefore, the measure of angle A is 60 degree.
