The value of c is approximately 9.24cm
Cosine rule
To get the approximate value of c, we will use the cosine formula expressed as:
[tex]c^2 = a^2 + b^2 - 2abcos \theta[/tex]
Given the following
a = 9cm
b = 6cm
theta = 73 degrees
[tex]c^2=9^2+6^2 -2(6)(9) cos 73\\c^2 = 81 + 36 - 108cos 73^0\\c^2=117 - 31.57\\c = 9.24cm[/tex]
HEnce the value of c is approximately 9.24cm
