Answer:

Step-by-step explanation:
Refer to file. Trying something different. Should be easier to read than text format and is easier than mathML.
Answers are like this: 1)Cos C 2)Cos B 3)Cos A 4)a 5)b 6)c all of them are different type of writing cosines law , just this.
Slope-intercept form looks like this: y = mx + b. For your equation, simply add 3x on both sides: y = 3x + 19.
For this case we have the following equation:
sin (40o) = b / 20
Clearing b we have:
20 * sin (40o) = b
Therefore, the length of the AC segment is given by:
b = 12.9
Answer:
the length of AC is:
b = 12.9
Answer:
15.7
