In ΔDEF, the measure of ∠F=90°, FD = 63 feet, and DE = 71 feet. Find the measure of ∠E to the nearest degree.

stepan [7]

Answer:

Step-by-step explanation:

∠F=90°, FD = 63 feet, and DE = 71 feet.

That's a right angle triangle also.

measure of ∠E to the nearest degree

sin∠E = 63/71

sin∠E = 0.8873

∠E= sin^-1 0.8873

∠E= 62.5°
