Answer:

  59.0°

Step-by-step explanation:

Many triangle solvers are available for your phone, tablet, or browser. The attachments show the input and output of one of them.

___

You can use the law of cosines to compute the result yourself.

  b^2 = a^2 + c^2 - 2ac·cos(B)

  cos(B) = (a^2 +c^2 -b^2)/(2ac) = (22^2 +18^2 -20^2)/(2·22·18) = 408/792

  B = arccos(408/792) ≈ 58.9924° ≈ 59.0°

Subtract.
Katena32 [7]
(8x - 8y + 9) - (5x - 8y - z) = 3x + z + 9

8 - 5 = 3
-8 - (-8) = 0
9 - 0 =9
0 - (-z) = z

so it is written 3x +z +9
