B. 4x - 1
C. 4x - 3
D. 4x - 4

D

Step-by-step explanation:

4 times x is 4x

4 times 1 is 4

4x - 4

4 * x and 4 * -1

which is 4x -4

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
