Answer:

Step-by-step explanation:
The area for a parallelogram is given by the formula:

Where b is the base length and h is the vertical height.
The base length is 16.9 while the vertical height is 8.7. Thus:

Multiply using a calculator:

Answer:
The answer to your question is: Ф = 43.95°
Step-by-step explanation:
Data
length = 18 ft
distance bottom to is 13 ft
x = angle = ?
Formula
cos Ф = opposite side / hypotenuse
Process
cos Ф = 13 ft / 18 ft substitution
cos Ф = 0.72 simplify
Ф = cos⁻¹ (0.72)
Ф = 43.95° result
Answer:
C
Step-by-step explanation:
It is not E becuase SQRT(97) is less than SQRT(100), SQRT(100) is 10,
SQRT(81) is 9 SO SQRT(97) is between 9 and 10, C.
Hope it helps :)
Answer:
17
Step-by-step explanation:
- 38 - 21 = 17
- 21 - 4 = 17
- The difference between each pair of numbers above is 17, so that is the common difference.
I hope this helps!
