Use the Law of Sines to find mZE. Round to the nearest degree.
D
30 mi
18 mi
78°
F
E

Step-by-step explanation:

recall law of Sines :  Sin(A) / a = Sin(B) / b

where F can be A, in above equation,  and then a = 30

we want to find E so that can be B, and b = 18

Sin(78) / 30 = Sin(B) / 18

solve the parts you can

0.03260 = Sin(B) / 18

18 * 0.03260 = Sin(B)

0.5868885 = Sin(B)

use  arcSin() to find angle of B

arcSin(0.586885)  = arcSin( Sin(B))  [ b/c arcSin is the inverse of Sin those go away, they cancel each other out ]

35.9365 = B

36° = B  ( and B = E in the given triangle )

∠E = 36°
