Answer:


c = 15.5

Explanation:

Using the Law of Cosines, c² = a² + b² - 2ab*cos(C), let's find c.

Where,

a = 15 ft

b = 20 ft

C = 50°

Thus:


c^2 = 15^2 + 20^2 - 2*15*20*cos(50)


c^2 = 625 - 600*0.6429


c^2 = 625 - 600*0.6429


c^2 = 625 - 385.74


c^2 = 239.26


c = √(239.26)


c = 15.5 (nearest tenth)
