Answer: First option.

Step-by-step explanation:

You can idenfity in the figure that \angle FCE is formed by two secants that intersect outside of the given circle.

It is important to remember that, by definition:

 Angle\ formed\ by\ two\ Secants=\frac{1}{2}( Difference\ of\ intercepted\ Arcs)

Knowing this, you can set up the following equation:

m\angle FCE=\frac{1}{2}(BD-FE)

Therefore, you must substitute values into the equation and then evaluate, in order to find the measure of the angle \angle FCE.

This is:

m\angle FCE=\frac{1}{2}(112\°-38\°)\\\\m\angle FCE=37\°
