Question

Find the value of e.

Answer 1

e = 15.29

Explanation:

using the law of sin, we can set this up as sin 40/12 = sin 55/e.

40 is the degree and is diagonal from 12. 55 is degree which is diagonal from e.

Cross multiplying sin40 with e, and 12 with sin 55, you get "e sin 40 = 12 sin 55"

Divide both sides by sin 40 and you get e = 15.29 :)
