Question

In ΔDEF, the measure of ∠F=90°, DE = 82 feet, and EF = 55 feet. Find the measure of ∠E to the nearest tenth of a degree.

Answer 1

Answer:

< E = 42.1°

Step-by-step explanation:

Law of sines

82/sin 90 = 55/sin E

sin E = 55 sin 90 / 82

sin E = 0.67

E = $sin^{-1}$ (0.67)

E = 42.1°

Answer 2

Answer:

< E = 42.1° is the answer
