Answer:
The length of side x is 22.91
Step-by-step explanation:
As per law of cosine
[tex]X = \sqrt{a^2 + b^2- 2*a*bcos\gamma}[/tex]
Where
[tex]gamma = 56[/tex] degrees
a = 20
b = 27
Substituting the given values in above equation, we get -
[tex]X = \sqrt{20^2 + 27^2 - 2*20*27*cos 56} \\X = 22.91[/tex]
Hence, the length of side x is 22.91
