The diagram shows the construction
.
If m∠ABC is 24°, then m∠FDE is
°.

The angle m∠FDE of the given construction is; m∠FDE = 24°
We are given the angle;
m∠ABC = 24°
Now, from the given image we can see that FDE is constructed the exact same way as ABC in such a way that all points correspond with each other in congruency and as such, we can say that;
m∠ABC = m∠FDE = 24°
