Answer: x = -3

Step-by-step explanation:

i simply divided by -7, in order to get x by itself.

-7/-7x = 21/-7

that cancels out the -7 on the left side, and leaves us with -3 on the right side!

x = -3

Answer:

16.4

Step-by-step explanation:

The law of cosines is useful here. It tells you ...

b^2 = 22^2 +10^2 -2·22·10·cos(44°)

b^2 ≈ 267.49

b ≈ √267.49 ≈ 16.35514

b ≈ 16.4
