Explanation:
From the description, you know:
1. Angle D.
The measure of the angle D = the measure of the angle A
∴ sin (D) = sin (A) = 4/52. Hypotenuse (side DE)
Since F is the right angle of the triangle, the side DE is the hypotenuse.
hypotenuse = DE = 30 units3. Segment EF
Angle E is opposite to angle D, hence segment EF is opposite to angle D.
sin(D) = EF/hypotenuse4/5 = EF/30EF = 30 × 4/5 = 24 units ← answer
