Answer:
22.62
Step-by-step explanation:
Cos=12/13
12/13= 0.9231
Cos^-1(0.9231)=22.62
B. -.0006
C. .28
Multiply 3 and 2 and you would get 6 then move the decimal 4 places to the left and you would get .0006
Multiply 7 and 4 and you would get 28 then move the decimal places 2 spaces to the left and you would get .28
Answer:
C) 12.2 cm
Step-by-step explanation:
To find the area of a square, you multiply length and width, which for a square, are the same. So to find the length of one of its sides, you have to take the square root of the area.

Let's find the difference between each number.
38-14=24
74-38=36
122-74=48
182-122=60
254-182=72
As you can tell, you're adding 12 to each difference before. The next difference would be 72+12=84. Let's add.
254+84=338
Now the next difference would be 84+12=96.
338+96=434
So, the next two terms are 338 and 434.
