What is the solution to 4/9*-10> */3-12?

The answer is 2 ( choose 2 )

and how we find this answer? the picture is clearly for that.

101.08 degrees to nearest hundredth.

Step-by-step explanation:

Use the Cosine Rule:-

25.7^2 = 10.7^2 + 21.4^2 - 2*10.7*21.4 * cos x   where x is the required angle.

cos x =     (25.7^2 - 10.7^2 - 21.4^2) / (-2*10.7*21,4)

=  88.04 / - 457.96

= -0.192244

x = 101.08 degrees
