Question

What is the length of side JN and JS (Round your answer to the nearest tenth.)

Answer 1

JN = 44.3

JS = 43.1

Explanation:

19) Use Law of Sines

sin53/39 = sin65/JN

JN = 39(sin65) / (sin53) = 44.26 ≈ 44.3

20) m∠N = 180 - 65 - 53 = 62

sin53/39 = sin62/JS

JS = 39(sin62) / (sin53) = 43.12 ≈ 43.1
