To find DE, you can use the Law of Sines:
sin(D)/DE = sin(E)/EF
sin(43)/DE = sin(62)/22
DE = 22 * sin(43) / sin(62) ≈ 15.6 in.
Therefore, DE is approximately 15.6 in.
So, the correct answer is: 15.6 in.
In triangle ΔDEF, m∠D = 43°, m∠E = 62°, and EF = 22 in. What is DE to the nearest tenth of an inch?
